MySql handle raised an exception (Exception: Connection is nullError

So I'm running multiple servers, all with shared DB's for EBS, I run with both Mysql & PlayerDatabase, however one server isn't doing what its supposed, files 100% sorted. I've double checked codes, db names & such. (Files are copied from a working server). 

Getting this message : MySql handle raised an exception (Exception: Connection is null) at Oxide.Core.MySql.Libraries.MySql+MySqlQuery.Handle () [0x0002b] in <79d157ef50864cd6a493ea45b8d9c402>:0

Hi all,

i was here to make also such a thread, i have over 150 plugins so was kinda hard to find. on my other servers it's working fine but on one server i get exactly the same message

MySql handle raised an exception (Exception: Connection is null) at Oxide.Core.MySql.Libraries.MySql+MySqlQuery.Handle () [0x0002b] in <79d157ef50864cd6a493ea45b8d9c402>:0

Same error this morning after server crash. In oxide/data after stop the server or unload the plugin delete the 2 enhanced ban files ****.Ip.json and EnhancedBanSystem_ID.json.

Restart the server. Fixed.

You dont loose your ban file in sql.

Regards.
