Err_Cache_Miss Error in Chrome: How to Fix It Fast
Websites feature all sorts of forms and input fields that a user fills in. Some of these fields may be common ones like a sign-in sheet while others may ask for information like a billing address, credit card numbers, feedback on a product, etc. The information is eventually submitted and that means it must be sent to a server. If all goes well, you get a message that the information was submitted.
ERR_CACHE_MISS
When the information fails to send, for whatever reason, you get the ERR_CACHE_MISS message in Chrome. When this happens, you usually need to enter the information again i.e., the entered information is lost. If you’re consistently getting this error, Chrome may not be able to communicate with the website, or the website may be having trouble. If it’s the former, there are a few things you can try to fix the problem.
What ERR_CACHE_MISS means and common causes
ERR_CACHE_MISS is a Chrome browser error that signals a caching or form-resubmission problem — it does not necessarily mean the website is down. You will most commonly see it after submitting a form (such as a login, checkout, or contact form) that uses an HTTP POST request. Chrome sometimes displays it alongside a “Confirm Form Resubmission” prompt, warning you that refreshing the page will resend the form data.
To understand why this happens, it helps to know what a browser cache actually does. When you visit a website, Chrome saves copies of images, scripts, and page data locally on your device. The next time you visit, Chrome can serve those stored copies (a “cache hit”) instead of downloading everything again, which makes pages load faster. A “cache miss” happens when Chrome looks for a stored response and cannot find one — or finds one it cannot use. For most page assets, a cache miss is invisible and harmless. The problem with ERR_CACHE_MISS arises specifically around form submissions.
Here is why forms are different: when you submit a login form, complete a checkout, or send a contact message, your browser sends that data to the server using an HTTP POST request. Unlike a normal page load (a GET request), POST requests carry data — your credentials, payment details, or message — that the browser is not supposed to replay automatically. If you hit the Back button or press Refresh after a POST, Chrome shows the “Confirm Form Resubmission” dialog rather than silently resending your data. This is a deliberate safety feature. ERR_CACHE_MISS appears when Chrome cannot construct a safe, cached response for that POST interaction and has no clean way to show you the result.
Two everyday examples make this concrete. First, imagine you click “Place Order” on a checkout page — the POST request fires, but before the confirmation page loads, your connection drops. Chrome is left with no response to cache, and you see ERR_CACHE_MISS.
Second, if you submit a contact form and immediately press Back and then Refresh, Chrome warns you about resubmission rather than caching the form result, and this interaction can surface the same error. In DevTools, you may see ERR_CACHE_MISS on individual sub-requests without any visible issue — that is usually harmless. The error becomes a real problem when it blocks the page that should confirm your action completed successfully.
In plain terms, Chrome cached (or expected to cache) a response from the server, but something went wrong before that response arrived or was stored correctly. The result is this error instead of a confirmation page.
Here are the most common causes to be aware of before you start troubleshooting:
- Corrupted browser cache or cookies holding on to a broken page state
- An outdated version of Chrome with unpatched caching or form-handling bugs
- Browser extension conflicts, especially ad blockers or privacy tools
- Network or DNS issues preventing a clean connection to the server
- An expired user session causing the server to reject the form submission
- Server-side caching rules or form-handling logic that are misconfigured on the website itself
If you use Firefox and see a “Document Expired” message in similar circumstances, that is the Firefox equivalent of this error.
1. Basic checks
Run the following checks before you try any of the solutions. The solutions target Chrome, Chrome’s settings, and your Windows network settings. In order to determine if they’re what needs to be fixed, these checks are essential.
- Make sure you’re able to access other websites i.e., you have internet access.
- Try submitting the form from another browser.
- Try to submit a similar form on another website if you can find one.
- Check if the website you’re submitting the information on is up by pasting its URL on Down For Everyone Or Just Me.
- Try connecting to a different network and submitting the form.
Assuming the problem persists only in Chrome, or it’s particular to a website and you have internet access otherwise, try the fixes below.
Reload the page first (soft reload vs. hard reload)
Before changing any settings, try the simplest fixes first. There are two types of page reload in Chrome, and they behave differently when it comes to caching.
A normal (soft) reload — using the reload icon in the address bar, pressing F5, or pressing Ctrl+R on Windows/Linux — tells Chrome to reload the page but may still reuse assets it has already stored in the cache. If the cache itself is part of the problem, a soft reload will not fully resolve it.
A hard reload — using Ctrl+Shift+R or Ctrl+F5 on Windows/Linux, or Cmd+Shift+R on Mac — forces Chrome to bypass its cached copies entirely and download a completely fresh version of the page from the server. This is the better first step for a cache-related error like ERR_CACHE_MISS.
Try the normal reload first, then a hard reload. If the error still appears after a hard reload, move on to the cache-clearing steps below.
2. Update Chrome
An outdated version of Chrome can cause caching, compatibility, and form-handling issues that trigger ERR_CACHE_MISS. Before diving into deeper fixes, make sure you are running the latest build.
- Open Chrome.
- Paste the following into the URL bar and tap Enter, or go to Settings > About Chrome.
chrome://settings/help
- Chrome will automatically check for updates and download any that are available.
- Click Relaunch once the update is installed.
- Try submitting the form again to see if the error is resolved.
3. Clear the webpage cache
It’s possible that you ran into a problem or the website threw some error while you were browsing it and it had an impact on whatever information you submitted.
- Visit the website that you want to submit information on.
- Tap the Ctrl+F5 keyboard shortcut and it will reload the website but ignore anything in the cache.
- Try submitting the form now.
4. Clear browser cache
Browser data for a website tends to build up. Ideally, it should purge itself but that doesn’t always happen. The Chrome cache may be the reason the form won’t submit.
- Open Chrome.
- Click the more options button at the top right (three dots).
- Select Settings from the menu.
- Under Privacy and Security, click ‘Clear browsing data’.
- Make sure every single option on the pop-up is selected.
- Click Clear data.
- Try submitting the form again.
5. Delete Chrome session cookies
Deleting the Chrome cache will sometimes still leave behind certain cookies. These cookies are not linked to users’ and their data which is why they aren’t removed.
- Visit the website that you’re getting the ERR_CACHE_MISS error on.
- Tap the Ctrl+Shift+I keyboard shortcut to open the Chrome console.
- Go to the Application tab.
- In the column on the right, select ‘Clear storage’.
- In the pane on the left, click the Clear all data button.
6. Disable extensions
Extensions can sometimes interfere with form submissions. These are normally extensions that block content on a webpage e.g., ad blockers. To be safe, disable all extensions and then try submitting the form.
- Open Chrome.
- Paste the following in the URL bar, and tap Enter.
chrome://extensions
- Turn the switch next to every single extension off to disable it.
- Relaunch Chrome.
- Try submitting the form.
7. What to do instead of disabling the form resubmission prompt
ERR_CACHE_MISS often appears alongside Chrome’s “Confirm Form Resubmission” dialog. That dialog exists for a good reason: it stops your browser from silently resending POST data — such as a payment, a login attempt, or a contact form message — without your knowledge. Suppressing it is not a safe general fix. If Chrome were to resend that data automatically, you could end up with duplicate orders, double charges, or multiple copies of the same form submission hitting the server.
Some older guides suggest adding a command-line flag to Chrome’s shortcut to bypass this warning. That approach carries real risk and is not reliably honored by modern versions of Chrome. We do not recommend it.
Instead, use these safer steps when you are unsure whether your original submission went through:
- Check for a confirmation email or order number. Most checkout and contact systems send an immediate confirmation. If you received one, your submission completed successfully — do not resubmit.
- Open the site in a fresh tab or a new browser session. Navigate back to the relevant page (your account order history, your inbox, or the form’s starting page) and verify whether the action was recorded before you try again.
- Only resubmit once you can confirm the first POST did not complete. If there is no confirmation email, no order in your account, and no other sign that the submission went through, it is safe to fill in the form again from scratch in the new tab.
If you own or manage the website where this error is occurring, the correct long-term fix is to implement the POST/Redirect/GET pattern described in the server-side section below. That approach eliminates the resubmission problem at its source by redirecting users to a confirmation page after a POST, so Chrome never ends up holding a POST response it cannot cache.
8. Disable system cache
Deleting/clearing the cache fixes a lot of web problems but sometimes the fact that files are being saved to the cache are the problem. You need to turn caching off for the website while you submit the form.
- Visit the website.
- Tap the Ctrl+Shift+I keyboard shortcut to open the Chrome web console.
- Click the little cog wheel button at the top right, or tap the F1 key.
- Select Preferences from the column on the left.
- Look for the Network group of settings.
- Enable the ‘Disable cache’ option.
- Do not close this window/panel.
- Submit the form on the website.
9. Reset Windows network settings (Windows 10/11)
While ERR_CACHE_MISS is a Chrome error message, it may have to do with problems your system is experiencing. It’s rare but not unheard of.
If you prefer a graphical approach on Windows 11, go to Settings > Network & internet > Advanced network settings > Network reset and follow the on-screen prompts. This resets all network adapters and returns networking components to their defaults.
Alternatively, the Command Prompt method below works on both Windows 10 and Windows 11:
- Open Command Prompt with admin rights.
- Run the following commands one by one to flush your DNS cache, release and renew your IP address, reset the Winsock catalog, and reset TCP/IP to its default state. Note that
ipconfig /allonly displays your current network configuration — it does not repair anything, so it is not included here. You may temporarily (1–5 seconds) lose internet connectivity.
ipconfig /flushdns ipconfig /release ipconfig /renew netsh winsock reset netsh int ip reset
- Restart the system.
- When you return to the desktop, open Chrome, and try submitting the form again.
10. Reset Chrome
This is the nuclear option but if you have Chrome sync enabled, you won’t lose data in the process.
- Open Chrome.
- Click the more options button at the top right (three dots button).
- Select Settings from the menu.
- Click ‘Advanced Settings’ on the Settings page.
- Scroll all the way to the bottom and click ‘Restore settings to their original defaults’.
11. Try a different browser
If none of the Chrome-specific fixes have worked, try submitting the form in a different, up-to-date browser such as Microsoft Edge, Firefox, or Safari. If the form goes through without any issues, the problem is likely limited to Chrome itself — its cache, an extension conflict, or a corrupted profile. That narrows the fix back to Chrome-specific steps like clearing profile data or creating a fresh Chrome profile. If the error appears in every browser you try, the issue is almost certainly on the website’s end rather than your machine.
If you own the website, check server-side caching and form handling
ERR_CACHE_MISS is not always a visitor-side problem. If you manage the website where the error is appearing, the following checks can help you identify and fix the root cause.
- Inspect the failing request in DevTools. Open Chrome DevTools (Ctrl+Shift+I), go to the Network tab, reproduce the error, and examine the response headers on the form submission request. Pay particular attention to
Cache-Control,Pragma, andExpiresheaders. - Review Cache-Control headers on sensitive pages. Form pages, login pages, and checkout pages should not be aggressively cached. Make sure these pages return appropriate headers such as
Cache-Control: no-storeorCache-Control: no-cache, must-revalidateso that browsers and intermediary caches do not try to serve a stale POST response. - Purge your caching layers. If your site uses a caching plugin (such as WP Rocket, W3 Total Cache, or LiteSpeed Cache), a server-level cache, or a CDN (such as Cloudflare), purge all caches and test again. A stale cached response can confuse Chrome into showing ERR_CACHE_MISS.
- Exclude POST-driven pages from aggressive caching. Configure your caching plugin or server rules to bypass caching entirely for pages that handle form submissions, logins, and checkout flows.
- Implement the POST/Redirect/GET pattern. After a form submission is processed, redirect the user to a separate confirmation page using an HTTP 303 redirect instead of returning the response directly to the POST request. This prevents the browser from holding on to a POST response that it cannot cache, which is the most common root cause of the “Confirm Form Resubmission” loop that accompanies ERR_CACHE_MISS.
If visitors are consistently reporting this error on your site, the combination of checking your response headers and applying the POST/Redirect/GET pattern will resolve it in the vast majority of cases.
Conclusion
The ERR_CACHE_MISS shouldn’t appear consistently for a website. If it does, it is highly likely that the website itself has a problem. You can try getting in touch with the website’s admin and let them know about the problem. From an end user’s point, the above fixes are all you can run to resolve the issue.
