vCenter Appliance 6.5 - vSphere Web Client / HTML5 Client (Fling Client) not working

[ProjectD22]

Hi there!

I just installed the vCenter Appliance 6.5 on a ESXi 6.5 Host. But now I'm not able to get the Web Client or the HTML5 Client working.

When I connect to them SSO pops up and I can login. After I logged in the HTML5 Client shows just a blank page.

The flash client just loads infinetly. Here's a screenshot of the flash client:

After a while I restarded the vCenter Appliance. But I got still the same problems.

What am I doing wrong?

Thanks in advance!

Login as Administrator@vsphere.local (or whatever you set your default SSO domain to be) and see if you experience the same thing.
