Original GitHub issue: https://github.com/open-webui/open-webui/issues/5097

In an offline environment (ethernet cable unplugged):

  • Ollama is running on http://localhost:11434/
  • Ollama is running inside Cmd Prompt
  • Ollama is NOT running in open-webui (specifically, llama models are NOT available)

In an online environment (ethernet cable plugged):

  • Ollama is running in open-webui (specifically, llama models ARE available)

I am running Open-Webui manually in a Python environment, not through Docker.

Please help. Thanks a million!
