I had the customer with the same issue. You must check your jts,ccm,qm and rm.log. We had following error message:
ERROR ronting.server.services.discov
ery.DiscoveryService - Server Error: Entry [5eac0b15f37d1132]
com.ibm.rdm.fronting.server.ex
ception.ServiceUnavailableExce
ption: Server state invalid: REQUIRES_MIGRATION
After finishing migration of RRC the issue has been fixed.

After opening an PMR, support came back right away with the solution (as did Krzysztof)... unfortunately for me it was RTFM:
I failed to run the RRC Migration steps (see the Migrating Requirements Composer section of the Upgrading to version 4.0 Interactive Guide). After running the migration tool at https://hostname.example.com:port/rm/web/projects/migration and restarting WebSphere the problem was solved.
This sounds like it could be a defect. If you haven't already, you should consider filing a workitem against Web UI -> Dashboards.
