Normal loading of Open-WebUI in localhost:8080
Actual Behavior
Open-WebUI was working fine and since last two days it stopped working all of a sudden. I set the right venv and go to the right project directory and type
open-webui servejust like I always did. The initial logs appear (see below) but it is never complete and seems like it is stuck. When I go tolocalhost:8080Open-WebUI is not available there.I even created a new venv and did a complete reinstall. Still it is not working.
