Hi navhawk80, this doesn't fix the problem.
After a few hours of tests, I finally find the problem. The problem is the Windows 🥇, it's not only nginx, traefik has the same issue ... When I switch to my ubuntu server everything was working well.

Hi,
Please disregard info I mentioned above.
Real fix was the script from here https://gist.github.com/pedrolamas/db809a2b9112166da4a2dbf8e3a72ae9
I put it into startup on my synology and now in LOGs external IPs are beaing reconnized correctly.
