@DjM:
Great news. THX

K+1? 
I have tested the 6.14rc6 in my lab environment and based on first tests with SSTP I’m not able to replicate the SSTP timing out issue, so it seems that it was really fixed.
So the final result is probably: SSTP is broken in ROS 6.8 - 6.13 (including), if there is sstp-server interface binding used.
