Since 2026-08-07 ~17:00 UTC, mautrix-discord bridges using a bot token fail to stay connected to Discord. The gateway connection dies about one second after READY, the bridge reconnect-loops every few seconds, and after ~1000 connection attempts Discord force-resets the bot token and emails you:
It appears your bot has connected to Discord more than 1000 times within a short time period. Since this kind of behavior is usually a result of a bug we have gone ahead and reset your bot's token.
