vSphere Web Client isn't accessible after vCenter Server 6. upgrade logo

In my previous post vCenter Server 6.* Upgrade I described process of upgrading vCenter Server 6.*. Right after upgrade I noticed that I can’t connect to vCenter Server using vSphere Web Client. It was a bit odd behaviour but I wanted to fix it.

Error I saw in browser was the following:

Here is the wirgo.log located in C:\ProgramData\VMware\vCenterServer\logs\vsphere-client.

In the logs there is one entry that is very interesting.

vSphere Web Client isn't accessible after vCenter Server 6. upgrade - 2

vSphere Web Client was running as NT Service\vspherewebclientsvc and it didn’t have correct permissions in C:\Program Files\VMware\vCenter Server\WebClient\server\work directory. Adding NT Service with full rights access to folder didn’t help as well. I changed it to main domain account (it could by any account with rights logon as a service and local admin rights on vCenter Server) and restarted vSphere Web Client.

Finally it started without any problems. I hope this might help someone else who might help same problem with vSphere Web Client and
