The guide is very comprehensive.
Hope it helps!
Yeah I’m going to comb over all of this information this weekend. Unfortunately, with my work schedule I haven’t had a chance to get home to try to fix the server side. I can report back then. 
The guide provided was detailed, but it’s not using the online admin portal. I’m not sure how to get to those command screens. Is it just windows command screen?
You’ll need to use ssh (may be available in the windows command terminal for you, or you could use WSL), or PuTTY.
Have you ever solved the problem? I have exactly the same issue, all working fine from my mobile via LTE but yellow icon in Beryl.
