xFi Advanced Security is blocking my server IP address

I need the following IP address - 206.81.1.116 - whitelisted when xFi Advanced Security is enabled.

This IP is currently being blocked by xFi Advanced Security when it is enabled. If I disable xFi Advanced Security I can get to the address without any problems. 

The same issue is was discussed here: https://forums.xfinity.com/t5/Xfinity-xFi/xFi-Advanced-Security-is-blocking-my-company-s-website/td-p/3305727

I tried calling and could never get transfered to someone who understood the problem.
