[08:22:56 ERROR]: [dynmap] ConnectionString: jdbc:mysql://localhost:3306/dynmap?allowReconnect=true

Steps to Replicate: /dynamap fullrender world

The message say. Setting in MySQL server or use flag.

I use flag and plugin don't auto-reconnect.

My MySQL server dont need bigger timeout.

no need to shout, wait_timeout is not a client setting, it is a mysql server setting. https://mariadb.com/docs/reference/mdb/system-variables/wait_timeout/

I think is solved thx but have another sql error "timeout"

On the third line of that error dynmap states what you can do to midigate this problem, did you do that?
