vc server is no longer valid

[Rozb123]

I have a problem with my VC and my virtual hosts.

Two weeks ago we’ve upgraded the physical host to 6.5u2 version, after the upgrade, we encountered with

connectivity issue to the virtual host ( SXi 5.5+6.0 versions), and In the VC client we get an error “the current session to the server is no longer valid”, error which we didn't have before the upgrade.

what happened with the servers? How can I fix it?
