Error login to SEPM 14 Console "Unexpected server error"

  Hi all,

  Yesterday we've upgraded our SEPM server from 12.1.6 to the newest version 14. Although the upgrade passed properly, now we are unable to login to SEPM console. We are constantly getting error "Unexpecteted Server Error". We've restarted SEPM service few times, restarted the whole server but without success. We've also made a repair of the SEPM, but again without success. It is strange, because a week ago we've upgraded another server with same performances from 12.1.6 MP6 to 14 and managed to login to the console without any problem.

   Please help us to resolve this issue.

   Thanks in advance!
