Invalid Database Event

[Melp_melp]

Hello

After a server disconnection event in a SCADA system. When server 1 wanted to go from MAIN to STANDBY state, an error occurred and the image warning jumped.

Server 1 went to invalid database state. The scada 1 service was turned off and re-uploaded, server 1 went to standby status.

Server 1 can be turned on as main without problems, and goes to standby if Server 2 is as Main.

Please your help with the possible causes of this problem and how to mitigate it. The log is shared around the event. which occurred between 10:40 a.m. and 10:47 a.m., the time at which the service was lowered.
