VCO SSO authentication issue

Hi,

I'm trying to setup VCO authentication using SSO. I have imported the necessary SSL certificates from VC in the "SSL Certificates" tab. Now when I try to register orchestrator in the "authentication" tab, I get the following error:

Server returned 'request expired' less than 2 seconds after request was issued, but it shouldn't have expired for at least 600 seconds.

Any idea what could be wrong?
