vCenter and PSC: IE Content Was Blocked

KB ID 0001440


I’d just installed a new vCenter and Platform Services Controller for a client this week. When I tried to access the web consoles I saw this.

Content Blocked IE

Content was blocked because it was not signed by a valid security certificate
For information see “About Certificate Errors” in Internet Explorer Help.

No amount of allowing certificates without revocation, and tinkering with the registry would let me in?


I cant believe how annoyingly simple it was to solve in the end! Go the the end of the URL and remove ‘/?csp’, problem solved
