What is the issue?

i start open-webui via below cmd first and then ollama service failed to up by using ollama serve. Output tells the port already in use. I got the same err reason if i change the order of launch(first ollama, then open-webui docker), please check and improve the integration of ollama and open-webui.
my cmd for start open-webui:
docker run -d -p 3000:8080 -p 127.0.0.1:11434:11434 -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always registry.cn-hangzhou.aliyuncs.com/kin-images/open-webui:git-18ae586
my cmd for start ollama:
ollama serve

Hi @zydmtaichi could you update Ollama to version 0.3.9?

Thanks, I solve the problem by using docker run -d -p 3000:8080 -v open-webui:/app/backend/data -e http://172.17.0.1:11434 --name open-webui --restart always registry.cn-hangzhou.aliyuncs.com/kin-images/open-webui:git-18ae586 and running the ollama cmd OLLAMA_HOST=172.17.0.1:11434 ollama serve.

the key of solving is virtual network addr for docker. It seems this is only way for program inside visit the host port outside under bridge mode.
