Session problems break automation at the worst time. This guide covers the most common Telegram session errors and how to fix them — plus prevention strategies.
Common Session Errors
SESSION_REVOKED
The account logged out from another device or the session was terminated. Fix: regenerate the session from a working login, then avoid opening the account elsewhere.
AUTH_KEY_UNREGISTERED
The account was deleted or permanently banned. Nothing to recover — replace the account.
Connection Timeout
Usually a proxy issue. Test the proxy, switch subnets, or use SOCKS5 instead of HTTPS.
Flood Wait Errors
Telegram is rate-limiting the account. Slow down your actions and let the account rest.
Preventing Session Problems
- One stable proxy per account — never switch IPs randomly
- Warm up new accounts before bulk actions
- Enable 2FA and store codes securely
- Regenerate sessions cleanly instead of reusing old files
- Log out all devices before transferring accounts
