ERR_CACHE_MISS is Chrome telling you that it expected to find a request in its cache (because the page asked it to) but couldn’t — and rather than resubmitting the data, it’s stopping. This most often appears when you go back or forward in your browser history on a page that used a form or a POST request. For the bigger picture, our Google Chrome Errors pulls everything together.
The most important thing to know: this error is usually not a Chrome problem. The page is the one telling Chrome not to cache the data. Chrome is doing exactly what it was instructed to do. Hitting the reload button with F5 resubmits the form and gets you past it — yes, even though Chrome asks if you’re sure.
The common scenarios
You submitted a form or completed a checkout, then hit Back: Chrome can’t show the previous page without resubmitting the form data. F5 → “Resend” in the dialog → the page reloads. If this was a payment form, don’t resend — just navigate to the site fresh.
A page you visited before now shows it: clear the site’s cache. Right-click the padlock → Cookies and site data → Manage on-device site data → delete. Then reload. The old cached data conflicted with what the server expected.
It happens on every site, not just one: Chrome’s cache itself is corrupted. Go straight to Fix 2.
Fix 1: Hard reload
Ctrl+Shift+R bypasses the cache and fetches the page directly from the server. This works for most ERR_CACHE_MISS errors that appear on initial navigation (not back/forward). If the error persists after a hard reload, the issue is beyond the cache.
Fix 2: Clear Chrome’s cache
Ctrl+Shift+Delete → change Time range to “All time” → make sure “Cached images and files” is checked → Clear data. The cache clear forces Chrome to request everything fresh from servers rather than using any locally stored data that may be corrupted or conflicting.
For a single site without clearing everything: open the failing site → F12 → right-click the refresh button → “Empty cache and hard reload.” This clears only that site’s cached data.
Fix 3: Disable cache via DevTools (for development work)
If you’re a developer seeing this constantly: F12 → Network tab → check “Disable cache” (top of the Network tab). While DevTools is open with this enabled, Chrome doesn’t use or write to the cache for any request. Useful for testing but not meant for normal browsing — disable it when done.
Extensions interfering with caching
Some privacy extensions and VPN extensions modify cache headers on responses, telling Chrome not to cache content that should be cached. When Chrome later expects that cache to exist (on back navigation) and it doesn’t: ERR_CACHE_MISS.
Incognito test (Ctrl+Shift+N) — if the error doesn’t appear in Incognito, an extension is the cause. Disable extensions one at a time in chrome://extensions to find which one.
Specific to POST requests: understanding why it happens
When you submit a form, Chrome sends a POST request (versus a GET request for regular page loads). POST requests are designed to transmit data that changes something on the server — placing an order, sending a message, updating a record. Chrome doesn’t cache POST responses because caching them would be dangerous: a cached version of a payment confirmation could be shown to users without the payment actually completing again.
So when you navigate back to a page that was served in response to a POST, Chrome has no cached copy and shows ERR_CACHE_MISS rather than silently resubmitting. It’s protective behaviour. The error itself is the correct response. The fix is understanding you need to navigate to the page again the normal way rather than using browser history navigation.
If it keeps happening on the same site
A site that consistently produces this error — even on fresh navigation, not just back/forward — may have incorrect cache-control headers in their server response. The site is telling Chrome the response was not cacheable, and when Chrome tries to navigate using history, there’s nothing to return to.
If you manage the site: check the response headers for the affected pages. Cache-Control: no-store prevents Chrome from caching anything and guarantees ERR_CACHE_MISS on back navigation. For pages that aren’t sensitive forms (marketing pages, informational content), adding Cache-Control: private at minimum allows Chrome to cache the response for that browser session.
Chrome flags reset
If ERR_CACHE_MISS appeared after experimenting with chrome://flags: navigate to chrome://flags → “Reset all to default” → Relaunch. Some experimental flags change cache behaviour in ways that cause persistent ERR_CACHE_MISS on sites that previously worked fine.
Related Chrome cache errors are covered in our Chrome not loading pages guide — when ERR_CACHE_MISS escalates to full page load failure rather than just a resubmit prompt, that guide covers the deeper cache and network stack diagnostics. For the development context, Chrome’s developer documentation covers the Network panel’s request waterfall view and how to read cache status indicators for each resource in detail.
Chrome profile and corrupted cache database
Chrome’s cache is stored as a database on disk. If this database becomes corrupted — from a hard shutdown during a write, a disk error, or a crash mid-cache operation — Chrome can’t read or write cache entries correctly, producing persistent ERR_CACHE_MISS on sites that should cache fine.
Clear the cache (Fix 2) addresses this in most cases. For persistent corruption that the cache clear doesn’t fully resolve: navigate to %localappdata%GoogleChromeUser DataDefault → find the “Cache” folder → close Chrome → delete the entire Cache folder. Chrome rebuilds a fresh cache database on next launch. This is more thorough than the Settings-based cache clear, which empties the cache but keeps the database structure.
Network proxy and cache interaction
Corporate proxy servers sometimes cache responses differently than Chrome expects. When Chrome sends a conditional request (asking the proxy for a cached version), and the proxy’s response doesn’t match what Chrome’s own cache expects, ERR_CACHE_MISS can appear as a proxy-cache negotiation failure rather than a local cache issue.
Test: disconnect from the corporate VPN or proxy and navigate to the site directly. If ERR_CACHE_MISS disappears, the corporate network’s proxy caching is causing the mismatch. This is typically an IT-side issue with proxy configuration rather than something users can fix locally.
Checking cache status in DevTools
F12 → Network tab → navigate to the failing page → find the request that shows ERR_CACHE_MISS → click on it. The Headers pane shows the request and response headers. Look for:
- Cache-Control: no-store — the server is explicitly saying don’t cache this
- Pragma: no-cache — older HTTP/1.0 header with similar effect
- Vary: * — very aggressive caching variation requirement that often prevents caching
If these appear in the response headers: the server is causing the error, not Chrome. If these are absent and the error persists: Chrome’s local cache has the problem, and the cache clear or folder deletion is the fix.
Incognito as a diagnostic and workaround
Incognito mode doesn’t write to the persistent cache (it uses an in-memory session cache that’s discarded when the window closes). For sites that consistently produce ERR_CACHE_MISS in regular Chrome but where you need to use them: opening those sites in Incognito avoids the cache issue entirely, at the cost of not persisting any session data between visits.
This is particularly practical for: multi-step checkout flows, form-heavy web applications, and bank or financial sites that explicitly prevent caching for security reasons. If these sites work cleanly in Incognito, that confirms they’re designed to avoid caching and the ERR_CACHE_MISS on back navigation is intentional site behaviour rather than a Chrome problem.
Service workers and cache API
Progressive Web Apps (PWAs) and modern web applications use Service Workers to manage their own cache independently from Chrome’s standard HTTP cache. A malfunctioning Service Worker can cause ERR_CACHE_MISS by intercepting requests and failing to serve them from its own cache while also preventing Chrome’s standard cache from being used.
Clear Service Workers: F12 → Application tab → Service Workers → for any registered service workers, click “Unregister.” Then also clear the Cache Storage in the same Application tab (under Cache Storage → right-click entries → Delete). After clearing, reload the page. The Service Worker re-registers fresh and the cache is rebuilt correctly from scratch.
Chrome update and cache format changes
Major Chrome updates occasionally change the cache storage format. During the transition, Chrome may not be able to read old cache entries, causing ERR_CACHE_MISS on sites where it expects a cached version. This typically resolves on its own as Chrome rebuilds the cache in the new format during normal browsing.
If it persists beyond 24 hours after an update: manually clear the cache (Fix 2) to force Chrome to rebuild immediately rather than waiting for organic rebuild. The manual clear after an update restart is one of those things worth doing proactively rather than waiting to see if ERR_CACHE_MISS becomes a persistent issue.
Redirects and cache conflict
Sites that use multiple redirects (HTTP → HTTPS, www → non-www, or marketing redirects) sometimes cache the redirect response but not the final destination. When Chrome returns to the page using cached navigation, it encounters the cached redirect but not the cached final response, producing ERR_CACHE_MISS at the redirect hop.
The fix: clear cookies and site data for the specific site (padlock → Cookies → remove the domain’s data) which includes the cached redirect responses. After clearing, fresh navigation re-establishes the redirect chain cleanly and Chrome correctly caches both the redirect and the final response.
When to just navigate fresh instead of troubleshooting
Sometimes the practical answer is to navigate to the site fresh rather than using back/forward navigation. For checkout flows, form submissions, and payment pages: after completing the action, bookmark the confirmation page URL or note the confirmation number, then close the page entirely. If you need to return to the site, navigate fresh from a bookmark or typed URL rather than using browser history. This avoids ERR_CACHE_MISS entirely for the scenarios where it’s most disruptive — payment and form pages that are designed not to be cached.
This isn’t “fixing” the error so much as understanding it well enough to work around it efficiently. The error exists because the site requires fresh navigation for safety reasons. Working with that design rather than against it is often faster than any troubleshooting approach.
Preloading and prefetch causing cache conflicts
Chrome preloads and prefetches pages it predicts you’ll visit next. When a prefetched page is a POST-dependent page, Chrome stores an incomplete or invalid prefetch response, and when you navigate to it normally, the cache entry conflicts with what the server expects — ERR_CACHE_MISS appears even on a first visit rather than only on back navigation.
Disable preloading if this is causing issues: Settings → Privacy and security → Cookies and other site data → “Preload pages for faster browsing and searching” → turn off. After disabling, Chrome requests every page fresh without prefetch conflicts. The tradeoff is slightly slower initial page loads (typically 100–300ms) without the prefetch acceleration. For sites that consistently cause ERR_CACHE_MISS on first visit, this preload disable is often the fix.
Testing across different Chrome versions
If ERR_CACHE_MISS is affecting a specific site consistently across multiple Chrome versions and the site’s developers confirm the headers look correct: try accessing the site via Edge or Firefox to confirm it’s browser-specific. Edge uses the same Chromium engine as Chrome and often shares cache behaviour; Firefox has independent cache handling and serves as the clearest comparison.
If it works in Firefox but not Chrome (or Edge): the issue is Chromium’s cache implementation for that specific site. Reporting via Chrome’s feedback mechanism (three-dot → Help → Report an issue) with the specific URL and reproduction steps contributes to Google’s bug tracking for Chromium cache issues.
Multi-account and multi-profile Chrome
If using multiple Chrome profiles (one for work, one personal), each has its own independent cache. ERR_CACHE_MISS in one profile while another profile loads the same site fine confirms the issue is profile-specific — that profile’s cache database is corrupted or has a stale entry that the other profile’s cache doesn’t have. The cache clear in Fix 2 needs to be done specifically in the affected profile, not in a different one.
Also note: Chrome’s Guest profile uses a completely fresh temporary cache. If the Guest profile loads the site without ERR_CACHE_MISS, the regular profile’s cache is the variable. Switch to Guest: click profile icon (top right) → Open a Guest window → test. If Guest works: the regular profile’s cache needs clearing. See also SSL Certificate Error in Chrome for a related case.
To summarise the core insight: ERR_CACHE_MISS is usually the correct behaviour rather than a bug. It’s Chrome’s way of saying “I was told not to cache this, so I don’t have a copy, and I won’t silently resend your form data without telling you.” Understanding that changes how you approach the error — less “how do I fix Chrome” and more “what was I doing that requires fresh navigation.” For the remaining cases where it’s a genuine Chrome or extension problem, the Incognito test immediately tells you which type of problem you’re dealing with. You might also run into Chrome Not Saving Passwords.
