EAC Server Side Error

Beginning on 3/05/2016 my Log.EAC.txt file began filling up with the following error:
3/6/2016 7:19:55 PM [Warning] [Cerberus] Connection attempt to the back-end failed! Reconnecting in 60 seconds…

Most of the time when a player connects I’ll get the following:
3/9/2016 2:40:17 PM [Warning] [Cerberus] Connection attempt to the back-end failed! Reconnecting in 60 seconds…
3/9/2016 2:40:19 PM [Error] [Cerberus] GetPlayerIDByGUID() returned 0! GUID: 76561198107476927.
3/9/2016 2:40:19 PM [Error] [Cerberus] [LogPlayerDespawn] Unknown Player GUID: 76561198107476927.

Rarely when a player connects I see:
3/9/2016 6:30:19 AM [Info] [UnregisterUser] GUID: 76561198284191594
3/9/2016 1:51:54 PM [Info] Back-end connection established.
3/9/2016 1:51:55 PM [Info] User status changed: 76561198029058052. Status: Authenticated Message: N/A

Thoughts on what’s going on? Any idea how to fix this?
