Amazon Workspaces and El Capitan

With OSX El Capitan (version 10.11 build 15A204h), I am unable to connect to my Amazon Workspace. The Workspace client (version gives me a weird error about a local certificate (and completely messes up the UI) and at other times is not able to verify the Internet connection.

Looking at tcpdump, it seems like the client normally tries to connect to which resolves to However for some reason the client is now connecting to which is what the IP resolves to in reverse. Visiting gives a certificate with the name and therefore makes the connection untrusted.

No idea how to workaround this. Help?
