Gemini Not Working? 7 Fast Fixes (2026)

Gemini refusing to respond, throwing an auth error, or just sitting there silently? You are not alone — Gemini breaks in a handful of predictable ways depending on whether you are using the web app, the mobile app, or the API, and most of them are fixable in a couple of minutes. Below are 7 fixes that actually work.

1. Sign Out and Back In

A stale authentication token is the single most common cause of Gemini suddenly refusing requests. Sign out completely, close the tab or app, and sign back in — this clears the token and resolves the majority of plain auth failures on its own.

2. Wait Out a Rate Limit

If you have been sending requests in quick succession, Gemini may be silently throttling you rather than showing a clear rate-limit message. Wait about 5 minutes before trying again instead of repeatedly retrying, which can push you further back in the queue.

3. Disable Your VPN

Gemini’s traffic routing is sensitive to VPNs and some proxy configurations, and this often shows up as a generic network error with no useful detail. Disable your VPN, reload, and test again before assuming the problem is on Google’s end.

4. Turn Off Browser Extensions

Ad blockers, privacy extensions, and some script blockers can interfere with Gemini’s web app in ways that look like the service itself is broken. Open an incognito or private window, which disables extensions by default, and test there — if it works, re-enable your extensions one at a time to find the conflict.

5. Force-Close and Clear Cache on Mobile

The Android and iOS apps sometimes fail silently with no error message at all. Force-close the app, then clear its cache from your phone’s app settings (not just force-close, since corrupted cache can survive that alone), and reopen it.

6. Regenerate Your API Key

If you are a developer and only recently created your API key, Google’s own status page has previously reported service issues specific to newly generated keys. Delete the key in Google AI Studio and generate a fresh one — this resolves key-specific serving problems that a new key sidesteps entirely.

7. Check Your API Key’s Permissions and Region

For Vertex AI integrations, confirm your service account has the Vertex AI User role under IAM in Google Cloud Console, since a missing role produces errors that look identical to a general outage. Also verify your project’s region supports the Gemini feature you are calling, since availability still varies by region.

If none of the above resolves it, submit a report through the Gemini Apps Community support thread with your exact error, device type, and what you have already tried — Google support actively monitors these threads for recurring patterns rather than one-off complaints.
