I'm having the exact same problem, and can also access http://63.135.170.51:51041/test without problems. I believe I have followed all instructions exactly, but I suppose it's possible I might have made an error somewhere.
Is there a (reasonably simple) way to validate whether or not one has a certificate issue?
