"https://ibb.co/7gp1cv5"

It says UpnP something but Im on LAN internet and on all pcs works fine, only on one It does not work as I said in my first question.

Hello, i have installed before plutonium bo2 and worked fine, but accidentally i delete all files from c:\BO2\plutonium and when i tried to install again it started the game but can't go in settings, and online. It says can not connect to servers.

Also i tried to remove all files of plutonium from pc like form %localappdata% and using ccleaner. reinstall again but without success. Idk what should I do please help.
Thanky You!
