I am using LWC connected to my local mysql Server.
After a long period of no actions the LWC (and some other plugins) need to reconnect. As it seems that PEX manages to establish a working connection atleast a part of LWC is not.
I think after the night all Plugins lost connection to the DB Server. i.e PEX is showing the reconnect attempt in the Logs:

From this time on - everytime someone attempts to protect a new chest with LWC, this error shows up in the console again. The Client gets the message "Created private CHest successful". But it does not register the Chest - there is no entry showing up in the DB and /cinfo returns "THis chest is not registered".
The already existing protections are working fine and /cinfo shows up all information about them. So i guess there is still some kind of DB connection or is this information about protected chests cached in the server?
Is there a solution to this problem?
Currently only a complete Server restart solves the issue needs the involvement of an server admin with shell access.
