How to Fix the ERR_CACHE_MISS Error in Your Browser

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.

ERR_CACHE_MISS

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.

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  • An outdated version of Chrome with unpatched caching or form-handling bugs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 10 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.

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.

  1. Open Chrome.
  2. Paste the following into the URL bar and tap Enter, or go to Settings > About Chrome.
chrome://settings/help
  1. Chrome will automatically check for updates and download any that are available.
  2. Click Relaunch once the update is installed.
  3. 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.

  1. Visit the website that you want to submit information on.
  2. Tap the Ctrl+F5 keyboard shortcut and it will reload the website but ignore anything in the cache.
  3. 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.

  1. Open Chrome.
  2. Click the more options button at the top right (three dots).
  3. Select Settings from the menu.
  4. Under Privacy and Security, click ‘Clear browsing data’.
  5. Make sure every single option on the pop-up is selected.
  6. Click Clear data.
  7. 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.

  1. Visit the website that you’re getting the ERR_CACHE_MISS error on.
  2. Tap the Ctrl+Shift+I keyboard shortcut to open the Chrome console.
  3. Go to the Application tab.
  4. In the column on the right, select ‘Clear storage’.
  5. 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.

  1. Open Chrome.
  2. Paste the following in the URL bar, and tap Enter.
chrome://extensions
  1. Turn the switch next to every single extension off to disable it.
  2. Relaunch Chrome.
  3. Try submitting the form.

7. Disable form resubmission prompt

The ERR_CACHE_MISS indicates a problem with form submission but the error message is shown by Chrome and not the website. It’s possible that Chrome is showing it to you because the response from the website didn’t come within a reasonable time or the response wasn’t what it was expecting. You can disable it but do so at your own risk. If you’re submitting credit card information, or something similarly sensitive, it’s best to skip this fix.

  1. Create a desktop shortcut for Chrome.
  2. Right-click the shortcut and select Properties from the context menu.
  3. Go to the Shortcut tab.
  4. In the Target field, add one space at the very end and then enter the following after it.
-disable-prompt-on-repost
  1. Click Ok.
  2. Use this shortcut to open Chrome.
  3. Visit the website and try submitting the form.

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.

  1. Visit the website.
  2. Tap the Ctrl+Shift+I keyboard shortcut to open the Chrome web console.
  3. Click the little cog wheel button at the top right, or tap the F1 key.
  4. Select Preferences from the column on the left.
  5. Look for the Network group of settings.
  6. Enable the ‘Disable cache’ option.
  7. Do not close this window/panel.
  8. Submit the form on the website.

9. Reset Windows 10 network settings

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.

  1. Open Command Prompt with admin rights.
  2. 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 /all only 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
  1. Restart the system.
  2. 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.

  1. Open Chrome.
  2. Click the more options button at the top right (three dots button).
  3. Select Settings from the menu.
  4. Click ‘Advanced Settings’ on the Settings page.
  5. 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, and Expires headers.
  • 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-store or Cache-Control: no-cache, must-revalidate so 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.
