Incidentally, my problem looks like this(???):

DDNS Error: Can not detect local IP

You are behind CG-NAT, so DDNS will not work in your case. This is usually the case with LTE/3G/etc This is not a spam

On my home router I use port forwarding normally. Smoothly.

Is there a solution for my case? Use proxy? DMZ? and How should I proceed?
