Quick Answer
Most Gemini errors come from Google account issues, workspace restrictions, or region locks. Sign out, sign back in, and confirm Gemini is available in your country and account type.
- Check status at status.cloud.google.com
- Sign out, clear cache, sign back in
- Confirm your Google account has Gemini access (age 18+, supported country)
Why This Happens
Gemini is tied tightly to Google accounts. Common issues: Workspace admin disabled Gemini, account under 18 hit age gate, region not supported, 2FA session expired, Google Cloud project billing stopped (for API users), or Gemini Advanced subscription lapsed.
Step-by-Step Fixes
Step 1: Check Google Cloud status
status.cloud.google.com — search "Gemini" or "Generative AI".
Step 2: Verify account eligibility
Go to myaccount.google.com → Personal info. Confirm age 18+. For under-18, parent must approve via Family Link.
Step 3: Check Workspace admin settings
If using a work/school account and see "Gemini is not available", the admin disabled it. Contact your IT admin or use a personal Gmail.
Step 4: Sign out of all Google accounts
Top-right avatar → Sign out of all accounts. Then sign in with ONE account to avoid account selector bugs.
Step 5: Clear cookies for google.com
Chrome: Settings → Privacy → Cookies → See all → google.com → Remove. Sign in again.
Step 6: Try gemini.google.com directly
Sometimes the embed on other Google products fails. Go directly to gemini.google.com.
Step 7: Check regional availability
Gemini is unavailable in some regions (EEA had early restrictions). Check support.google.com/gemini → Supported countries.
Step 8: For API errors
403 PERMISSION_DENIED— enable Generative Language API at console.cloud.google.com/apis429 RESOURCE_EXHAUSTED— you hit quota; request increase or upgrade billing400 INVALID_ARGUMENT— check your model name and request body
Step 9: Regenerate API key
aistudio.google.com/apikey → Delete key → Create new key. Update in your app.
Step 10: Enable billing
API requires billing enabled even for free tier. console.cloud.google.com/billing — link a valid card.
When to Contact Support
- Workspace says Gemini enabled but you still see "not available"
- API returns
500for 1+ hour - You paid for Gemini Advanced but features don't activate after 24h
- Account flagged as "compromised" without explanation
Support: support.google.com/gemini
Prevention Tips
- Use personal Gmail for Gemini if Workspace admin is strict
- Enable billing alerts in Google Cloud to avoid quota surprises
- Don't share API keys in public repos — Google auto-revokes exposed keys
- Keep one primary Google account signed in to avoid conflicts
