WebInterface not loading

[NiiroIjin]

Hello all,
long time user of SABNZBD and now recently I have a big issue.
It happend overnight (ofc) the one day everything was fine, service was running, webinterface was accessible.
Then the next day (i did not do anything to the setup) but found out later that Windows seems to had an update installed to Windows 11 24H2.
Ever since then, I am unable to open up any web interface of services running on my PC. Not SABNZBD, not Emby not Plex, nothing comes up, no browser that I try is able to open these interfaces.
Fun fact, the service itself is up and running, I can let SABNZBD download nzbs without a hitch, and i can access my emby library from my smart tv as well and play movies.

Technical Info:
OS: Windows 11 24H2 (all available updates installed)
All drivers also up 2 date
SABNZBD: Version 4.4.0 installed
Antivirus: Windows included Defender (also tried to disable this temporarly)
Firewall: Windows Firewall (SABNZBD is listed there and is setup to communicate with the internet)
Port: 8080 (also tried moving it to another port via INI edit)

What else info do you need to, hopefully, give some hints or tips on how to fix this?

Kind regards,
Niiro

Did you reboot the system?
Did you double click the icon in the system tray?

Yes, I did multiple reboots, and yes I clicked the tray icon.
I also tried to put in my ip adress in the browser myself.

Also tried to uninstall and reinstall the app, to no use. Same issue. Webpage opens, I see the app fav-icon and it is loading forever, not showing the web-interface.

In the directory of the sabnzbd.ini there is the logging, maybe it tells you something.

You could also run the SABnzbd-console.exe and see if anything out of the ordinary is printed.

Have you tried a Safe Start for Sab? It resets default settings.
Maybe there's some wrong host setting in your sabnzbd.ini.

I can not download anything. I use Newshosting. When I try to open the interface this is what I get.

Please help. I am not computer savi when it comes to nzb. I am running Windows 11

I was able to fix it. When I went back through the setup phase, I noticed that something had changed my port to 563. I changed it back to 8080 and it immediately started downloading.

This topic can be closed. It wasn't an error on the tool side, my windows was acting up.
After moving the whole thing to a UnraidOS it works like a charm.
