NAT means that you have a system in front of you (like a router).
The request don't reach you directly, but the router.
If you can configure that router to forward the requests to you, then you can solve your problem, otherwise not.
As you can see, HFS detected not 1 but 2 NATs.
It is probable that you can configure the first one and not the second.
Some providers prevent you from getting requests, and thus run "servers".
You have to ask your internet provider about it.
Did you click "verify" ?
the notification system of the forum is not working.
my suggestion is that you post on github your other questions.
