Built out a new server 2016 with remoteapp delivering a browser (firefox). It's been working perfectly for 2 weeks but now I find that I cannot add new connections using the windows 10 remoteapp and desktop connections.
When I try to add the URL - https://server.domain.com/RDWeb/Feed/webfeed.aspx I get a "There is a problem with this connection's security certificate" message.
I'm using a valid wildcard SSL cert and under deployment properties - certificates it says trusted for connection broker and web access (not using gateway).
Connections already created in the last 2 weeks are still working perfectly. I've tried adding the cert to the local computer trusted store on the server and desktop trying to establish a connection but I still get the same error.
Help! TIA!
