Hi there, I'm having an issue with my server that I was hosting on a personal Linux VM, it was previously working without any issues and randomly stopped working. 

Whenever trying to start my own private server with my world, I get the error:

[2020-05-20 19:43:26 ERROR] DBStorage chain is invalid. Possibly encryption-related, or bad DBStorageConfig passed. Reason: Unable to decipher/decrypt LevelDB.
[2020-05-20 19:43:26 ERROR] Network port occupied, can't start server.

Creating a new world doesn't cause any issues however when I attempt to change the server name in the server.properties to my original world, this error appears. There is no other application on the same port, and changing the host port has no effect. 

EDIT: Seems the issue comes down to being a corruption problem, make sure you have backups....
