Octoprint service starts, but unreachable on localhost (Windows)

What is the problem?

I've installed OP on my Windows 10 laptop, it worked great at first. I installed bed level visualizer, added some commands in the config.yaml, then restarted from the UI in localhost:5000. After that, I haven't been able to open up the UI again. Everytime I try to reach it at localhost or typing in 127.0.0.1 I get an unable to connect page on firefox. Same in Edge and Chrome.

What did you already try to solve it?

I've stopped the server, restarted it, restarted my computer and tried again, but still no result. The wrapper log says that there hasn't been a problem with starting the server and service.

Have you tried running in safe mode?

Not sure how to without access to the UI.

Did running in safe mode solve the problem?

NA

Systeminfo Bundle

can't grab it

Additional information about your setup

newest octoprint version from windows installer

check octoprint.log for errors in the basedir\5000\logs folder and make sure any firewall software isn't blocking port 5000. the installer should have added exceptions to windows default firewall but if you have other security software check its settings.

If you manually added things to the config.yaml, if you messed somethingnuo, that can keep octoprint from starting as well
