No bot bridging M->T after network outage

[pacien]

After a network outage, the bridge stops relaying messages from Matrix to Telegram through the bot's account. Messages from Matrix to Telegam are still being sent for users who logged in with their own account. Messages from Telegram to Matrix are still working.

The exceptions in the log seem to indicate some problem related to locks.

The bridge then have to be manually restarted for the bridge to fully work again.

Log snippet with exception trace:

Happened to me too. Restarting the bridge was enough to fix.

Encountering this as well, but a restart does not help.

I found out that it was enough to remove all the contents of telethon_sessions table, the bot reauthenticated and it works fine now.
