Hi @juliomoralesp, i cannot reproduce it locally.

Do you see any errors in the UI?
Anything in the log? (See %localappdata%\NETworkManager\NETworkManager.log)

Can you try the latest Portable version: https://github.com/BornToBeRoot/NETworkManager/releases/download/2026.7.16.0/NETworkManager_2026.7.16.0_Portable.zip

Note: Some firewalls can detect and block an IP/Port scan. Then the result will be empty and everything is shown as "closed".

Unfortunately, there's no video attached, no log file, no crash report, and no steps to reproduce the issue. I don't know how I can help here :)

I'm closing this issue because I cannot reproduce it and have no information about what's happening.
Anyway, in the next release there are some improvements to the scanning logic. Feel free to try the next (pre-)release once it's available.
