[Observium] Systems no longer show up

Good day everyone!

We are no longer seeing anything via the webui. I suspect it is due to a loss of network connectivity over the weekend. Seeing the following in the db.log now:

Failed dbQuery (#2006 - MySQL server has gone away)

Initial investigation seems to suggest that the client has become disconnected from the mariadb server (they are the same system) and so I'm wondering if there is an easy recovery method. Restarting services has not worked and the server has been rebooted. Still no change. Any help is greatly appreciated!

Cheers, Jason
