Quick answer

"Tabnine authentication timed out after 5 minutes" appears when the browser login is not finished or the local callback is blocked. Fix it with a fixed callback port or a token.

Most likely fix: Retry the login

How to fix it

Try these in order — the most common fix is first.

  1. 1. Retry the login

    1. Run: tabnine auth login
    2. Finish the browser step promptly

  2. 2. Fix the callback port

    1. Set OAUTH_CALLBACK_PORT to a fixed port and allow it in your firewall
    2. Optionally set TABNINE_LOGIN_CALLBACK_HOST (default localhost)
    Did this fix it?

  3. 3. Use a token instead

    1. Set TABNINE_TOKEN to a PAT
    2. Or choose Paste Tabnine access token (PAT)
    Did this fix it?

  4. 4. Remote SSH, Docker or WSL in an IDE

    1. VS Code: Command Palette > Tabnine: Sign in using auth token
    2. JetBrains: Search Everywhere > Tabnine: Sign in using auth token
    3. Click Get auth token, copy it, paste it into the popup
