VMware Update Manager Error - Session is not authenticated Print E-mail

 

I recently came across the following error with VMware Update Manager 4...

 

There was an error connecting to the VMware vCenter Update Manager [servername:8084].

: Vmomi.Fault.NotAuthenticated : The session is not authenticated.

 

 

 

 

 

 

 

 

 

 

 

 

No related changes to VUM or vSphere in general had been made that would affect it. However the user account I was using and logged into vSphere with had its password changed, which assumably was the cause. Restarting the "VMware Update Manager Service" resolved the problem.

 

 

First I checked the vSphere client plugin. It was showing an error "Plug-in is unavailble for the following server(s): servername". 

Attempting to right click and enable the plug-in resulted in the same error.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Checking the Update Manager logs there were messages relating the problem to connections issues with Update Manager and the client.

I restarted the "VMware Update Manager Service".

 

 

Then went back to the vSphere client and enabled the "VMware Update Manager" plug-in, which enabled fine.

All update manger tabs in vSphere client appeared and it has been working find since.

 

 

There is a related VMware KB on this error but it did not apply to my issue.
