Just installed wac 2511, I just get 'The SSL connection could not be established, see inner exception.'
Has anyone else seen this behaviour?

Update: It works with the self-signed certificate. How can I get Windows Admin Center to use a third-party certificate without issues?

For me it worked if I got cert without any properties (like UO, country, city etc.) except host name (CN), leave everything else blank. adding any properties break cert it seems.

    That doesn't work for me. I've only added the CN (common name), without any other properties, but it still doesn't work.

    I reactivate the self-signed certificate and that works.

     

    Any suggestions?

    Aren't these required for a 3rd party certificate?
