Screenshots / Server log

[09:39:16] [Server thread/INFO]: KiwiFrogg issued server command: /ai challenges

Expected behavior / Additional context

It looks like the database disconnects and then bentobox can’t reconnect, the other plugins using the database do not have the same issue. Looking at the logs it effects more than just challenges. Also, I tried with a dev version of challenges same issue.

Well, its been 15hours uptime, the database is still connected and there is only 1 on the list localhost:34024 | bentobox | Sleep | 00:01:22 .

I’d call that fixed.

Ok it is running, and I can confirm just 1 connection,   | 4181 | mc | localhost:34024 | bentobox | Sleep | 00:00:59 and everything is working fine so far. We wont know for at least 12 hours, with no resets.
