Hi there
I have setup a new vCenter 6.0 Server on Windows Server 2012 R2. After the initial inistallation of vCenter, I was able to access vSphere Web Client via my browser (https://vCenter Server IP/vsphere-client) using the SSO Admin user login credentials, for vCenter Server 6 (administrator@vsphere.local).
I was half way into configuring SSO (had already added the new identity source to the default domains by clicking “Add to default domains” in the top bar) and next step was to Assign Permissions and I had to go out for something. Came back and the page had timed-out so when I am trying to access the Web Client again from my browser, I am getting error "Unable to connect....Firefox can't establish a connection to the server at vcenter.test.com. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection."
I can access the vCenter Server from vSphere Client but cannot configure SSO from here.
