Original GitHub issue: https://github.com/open-webui/open-webui/issues/453

When running the webui directly on the host with --network=host, the port 8080 is troublesome because it's a very common port, for example phpmyadmin uses it.

It would be nice to change the default port to 11435 or being able to change it with an environment variable.

For now I can't run the webui since the default docker run command doesn't work (Server connection error) and making it run on the host conflicts with phpmyadmin.

I'm assuming you're using docker with --network=host. I'm curious, why -p <new-port>:8080 doesn't work?

I have this PR https://github.com/ollama-webui/ollama-webui/pull/454. Using SERVER_PORT you can modify the default port from 8080. Can you test ?

I tried to build the image but the build fails (Ubuntu 22.04).

Didn't get any issue here. The build was successful 🤔 . Can you prune older images and retry?
