# Open WebUI: 
# Server Connection Error
# If you're experiencing connection issues, it’s often due to the WebUI docker container 
# not being able to reach the Ollama server at 127.0.0.1:11434 (host.docker.internal:11434) inside the container . 
# Use the --network=host flag in your docker command to resolve this. Note that the port changes from 3000 to 8080, resulting in the link: http://localhost:8080.
# Example Docker Command:

# docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always ghcr.io/open-webui/open-webui:main




# remove something

docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 ghcr.io/open-webui/open-webui:main

# docker run -d --name=maxkb -p 8080:8080 -v ~/.maxkb:/var/lib/postgresql/data cr2.fit2cloud.com/1panel/maxkb

# change local port to: "8081", do not change container port: "8080"
