Issue Plesk login IP detection

[shima]

Greetings,
After upgrading plesk to Obsidian, I'm facing with a unusual problem:
I can't login to the plesk as admin, since it detects Gateway IP instead of mine!
No admin can login to the plesk due to the wrong IP.
P.s I could login to the plesk Onyx with the same config.

I have the same problem with Plesk windows
