[Blink] sip2sip.info unreachable via TLS connection

[Michael Nagie]

Hello,
I need a little help.
I've been unable to connect to sip2sip.info via TLS with my Cisco 
SPA504G device for a couple of days now.

sip2sip.info status says: all systems operational
yet I can't establish a secure connection.

If I choose TCP transport protocol then it can connect otherwise with 
TLS it says 'Failed - Not Reachable'

Here's my configuration, it's pretty basic, I didn't change much:
