Fix: Telegram Userbot Session Expired
Fix userbot authentication issues. MTProto session renewal, 2FA verification, and flood wait errors.
Telegram MTProto sessions can expire for a few reasons: too many concurrent sessions, password change, or Telegram's server pruning idle sessions.
Confirm the symptoms
- Dashboard shows "Disconnected" with "Session expired" subtext.
- Userbot commands silently ignored.

- Re-authenticate from dashboard with SMS code + 2FA.
Root causes
1. Too many concurrent sessions
Telegram caps active MTProto sessions per account.
- Drop unused sessions in Telegram → Settings → Devices.
2. 2FA password change
Changing 2FA invalidates existing sessions.
- Re-authenticate with new password.
3. Long idle period
Sessions inactive for weeks can be pruned.

4. Manual termination
If you tapped "Terminate" in Telegram → Devices on the userbot session.
- Re-authenticate.
