Hi, My code is trying to connect to the Disqus API (https://disqus.com/), but I have started getting an "Invalid certificate received from server" error. I've tried running mozcerts --sync to load the latest Mozilla root CAs, and connecting to other SSL/TLS works fine. I am using Mono 3.0.7, but I encounter the same issue on Mono 3.0.10. Strangely, running tlstest doesn't output anything apart from the URL:
23:21 daniel@dan /tmp % mono tlstest.exe https://disqus.com/ https://disqus.com/ But it works fine for other servers: 23:22 daniel@dan /tmp % mono tlstest.exe https://google.com/ https://google.com/ [Subject] CN=*.google.com, O=Google Inc, L=Mountain View, S=California, C=US ...etc... Below is the exception I'm getting: System.Net.WebException: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure ---> System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server.
