How to Fix Google Play Store Error 491
What error 491 means
Error 491 is a Google Play Store download error that makes installs and updates impossible. Unlike codes that let a download start and then fail partway, 491 typically kills the attempt up front: you tap Install or Update, and the pop-up appears instead of progress. It can hit a single app, but more often it blocks every download on the phone.
The root cause is usually the account link rather than the app or the phone itself. Your phone holds a token that authorizes downloads against your Google account; when that token corrupts — or the sync between your device and Google’s download servers drifts — the servers refuse every new install and the store reports the refusal as 491. Corrupted Play Store cache, stale Google Play Services data, an interfering VPN or private DNS, and tight storage can all produce the same symptom.
The good news is that 491 is very fixable. Because the fault lives in temporary data and account state rather than hardware, the standard Play Store repair sequence — restart, wipe the store’s cache and data, clear the Play Services cache, and above all remove and re-add the Google account — resolves it for most people in about fifteen minutes, without losing any personal data.
Common causes
- Corrupted account token: the download authorization between your phone and Google’s servers has gone stale, so every install or update is refused — the classic 491 trigger.
- Corrupted Play Store cache or data: broken temporary records in the store app can block new downloads before they start.
- Stale Google Play Services cache: Play Services handles download authorization in the background, so bad data there surfaces as store errors even when the store app looks fine.
- VPN or private DNS interference: traffic routed through another country, or a private DNS that blocks Google endpoints, can make Google’s servers refuse the download.
- Low storage or outdated software: a phone with less than about 1 GB free, or an outdated Play Store or system version, can trip download failures the store reports as 491.
How to fix error 491 — step by step
Work through these fixes in order. Most people are fixed by step 4.
- Restart your phone. Press and hold the Power button (or swipe down from the top of the screen and tap the power icon), then tap Restart. A reboot clears hung download sessions and stale service state that can keep error 491 reappearing on every attempt. Once the phone is back on, open the Play Store and retry the download — it is quick, harmless, and resolves a small share of 491 cases outright.
- Clear the Google Play Store’s cache and data. Open Settings, then go to Apps (or Apps & notifications), then See all apps. Tap Google Play Store, then Storage & cache. Tap Clear cache first, then Clear storage (or Clear data) and confirm. This wipes the corrupted temporary download records behind error 491 without touching your installed apps, photos, or personal data. Reopen the Play Store, accept the terms again, and retry the download.
- Clear the Google Play Services cache. In Settings > Apps > See all apps, find Google Play Services, tap Storage & cache, and tap Clear cache — clear only the cache, not all data, since Play Services holds sync state other Google apps rely on. Repeat for Google Services Framework (tap the three-dot menu and choose Show system if it isn’t listed). Play Services handles download authorization behind the scenes, so stale state there can reproduce error 491 even after the store’s own data is wiped. Restart the phone and try again.
- Remove and re-add your Google account. This is the targeted fix for error 491, because the error usually means the account token your phone uses to talk to Google’s download servers has gone stale. Go to Settings > Passwords & accounts, tap your Google account, then Remove account. Restart the phone, return to Settings > Passwords & accounts, tap Add account > Google, and sign back in with the same account. Rebuilding the account link clears the server-side glitches that cache clearing alone cannot reach.
- Switch networks and disable your VPN. Error 491 can piggyback on connection problems — try the download on mobile data instead of Wi-Fi (or the reverse) in Settings > Network & internet. If you use a VPN or a private DNS, turn it off temporarily: a VPN routing through another country can make Google’s servers refuse the download. If the install succeeds with the VPN off, you have found the culprit, and you can reconnect afterward.
- Free up storage and refresh the Play Store itself. Keep at least 1 GB free — Settings > Storage shows what is eating space; delete unused apps and old downloads. Then in Settings > Apps > See all apps, tap Google Play Store, tap the three-dot menu, and choose Uninstall updates, which rolls the store back to its factory version so it can update itself cleanly. Also check Settings > System > System update for pending OS patches. A factory reset is the last resort — back up everything first.
Did this fix it? Quick checklist
- The app downloads or updates without the 491 pop-up
- New installs and updates work, not just retries
- The Play Store opens, browses, and searches normally
- Downloads complete over both Wi-Fi and mobile data
If error 491 still appears after all six steps, double-check that you know the password for the Google account on the phone, then remove and re-add the account one more time — the first attempt sometimes fails to rebuild the token if the network was flaky. As a final measure, back up your data and consider a factory reset (Settings > System > Reset options > Erase all data).
Frequently asked questions
What does Google Play Store error 491 mean?
Error 491 means the Play Store cannot complete any app download or update — every attempt dies with a 491 pop-up instead of installing. It’s most often caused by a corrupted account token between your phone and Google’s download servers, though stale Play Store or Play Services cache, account sync problems, and low storage can also trigger it. The hallmark of 491 is that it blocks downloads entirely rather than failing partway.
How is error 491 different from error 492?
Error 491 points at a broken account link: downloads and updates are impossible because your phone’s download authorization has gone stale. Error 492 is a storage-side install failure. They overlap, but 491 is the one fixed most reliably by removing and re-adding your Google account, while 492 responds more to freeing storage and clearing the Download Manager.
Will removing my Google account delete my apps or data?
No. Removing your Google account from the phone only unlinks the account on that device — your installed apps stay installed, your photos and files stay put, and your purchases remain tied to the account. When you sign back in, everything reconnects. Just make sure you know the account password before you remove it.
Can a VPN cause error 491?
Yes. A VPN can interfere with the Play Store’s connection to Google’s servers, especially when it routes traffic through another country — Google may then refuse the download and report it as 491. Disconnect the VPN, retry the download, and turn the VPN back on once the install finishes. The same goes for private DNS settings that block or redirect Google traffic.
What if error 491 keeps coming back after every fix?
Recurring error 491 usually means there is an ongoing problem with your Google account sync or a persistent storage shortage. Remove and re-add your Google account again, make sure you have at least 1 GB of free storage, and uninstall the Play Store’s updates so it rebuilds itself. If the error survives all of that, a factory reset — after a full backup — is the most reliable permanent fix.
