CAS stopped working after getting added to RUM Console


After adding CAS under RUM Console it turn red and stopped working. Even the services restart/server reboot isn't helping.

Received the following error in logs.

Stop the CAS service and Watchdog service, open cmd.exe navigate to C:\Program Files\Dynatrace\CAS\server and run the following command:

runServer.bat -M

when done close cmd.exe and start Watchdog and CAs services.

I did the activity but again the same status, the service starts and then stops by itself

What does the server.log say now?

Issue is resolved now, the DB Schema was corrupted and reinstalling CSS resolved it. Thanks

Fixed by reinstalling CSS and creating new database as DB schema was corrupted during previous installation.
