Session with Update Manager (5.5.0.19906) is no longer valid and a VMWare cert.

Hi,

just did a upgrade to 5.5 including generating CA signed crts and all that.

No issues with any other services, but since the client is still required for anything useful related to host upgrading the VUM plugin need to be installed.

Sorry for the image overload, but what the VUM plugin basically did was to replace our CA signed cert with some standard VMWare one, generating a security warning.

Besides that, the Update Manager has begun to randomly crash with a error message saying that the session is no longer valid.

Installing our CA signed crt with a unique SDN again fixed the security warning, but not the "invalid sessions".

Reinstalling the VUM doesn't help, and there is no antivirus application running.

VMware vSphere Update Manager Extension VMware, Inc. 5.5.0.19906 Disabled VMware vSphere Update Manager extension Plug-in is unavailable for the following server(s) :- SERVERNAME

Any ideas?

Thanks in advance.
