Empty Orchestrator Control Center

Hi,

I have deployed a vRO 7.3.

After a deployment I logged in to Orchestrator Control Center as root and configured vSphere Authentication mode as described here:

Configure a Standalone Orchestrator Server with vSphere Authentication .

Now I am not able to configure anything in Orchestrator Control Center.

When I Log in with SSO user who is member of configured Admin group I see empty page (see screenshot). There is the only header and footer but no link.

And I am not able to log in to Orchestrator Control Center as root because the login page is from sso and it cannot authenticate appliance local user.

Any idea what is wrong?

Thanks for help.

Pavel
