Hello
I have 2 servers connected with the mysql database
that's it ss

Please help

That’s a warning, not an error.

The plugin should operate as normal.

Indeed, should be fine to ignore, although it might suggest that your server is lagging a bit.

How can I fix it

The above change will fix the warning message from appearing.

However, it won't fix the underlying issue, which is that your MySQL server is taking a long time to respond.

Just a note: when this occurred (could be a cause or an aftermath issue) all players were booted from my server and after it cleared up they were able to rejoin.

This could be due to a lag somewhere, a disconnect and due to low TPS maybe it just booted players?

Uhh, I don't think players disconnecting would be caused by any errors here - more likely the other way around.

i.e. the issue that caused players to disconnect also caused the LP warning
