Strange Error

My Matchserver is running fine, after 3 days of running, I can't see the server on my client. When I checked my server it says "[CRITICAL ERROR] Can't connect to DBMS."


It is the second time I experienced it. Below here is some preview of my logs.

Code:

It can't connect to the DBMS for around 15 mins, then after such time, it becomes stable.


Any ideas regarding this issue? I need a hand over here. Thanks!
