HTTP 500 Internal Server Error after reboot

[CommunityUser]

We are having difficulty on our AppDynamics server after a reboot this morning. Database and Application services start but when we get "HTTP 500 Internal Server Error" when we try to connect.

The controller can take a few minutes to fully initialize, and my
experience is that during part of that time you can get this message. Have
you waited at least 10 minutes?

Yes, it's been over an hour now...

- database.log , startAs.log and 4-5 rencet server.log under <controller_install_dir>/logs path
