How to Fix Ollama Port Not Connecting to Open WebUI Error

Running the Large Language Model (LLM) for running self-hosted AI is now widely used by users. Ollama is one popular tool that provides an environment in which to run different LLMs locally. It can be installed on Linux, Mac, and even on Windows.

Ollama is an environment for running the LLMs, and it does not offer a graphical interface to initiate the chat like ChatGPT. To do so, you need to install Open WebUI. After connecting Open WebUI with Ollama, you can use it like a local ChatGPT.

If you have installed Ollama on your Mac and are not connecting to the web UI or other chat application, this is a common issue many users face. However, the issue won’t happen if you have installed both Ollama and Open WebUI on the same machine. But if both apps are running on two different machines in your local network, you may face an issue connecting Open WebUI with Ollama due to the Ollama Port not being available to other devices.
