Original GitHub issue: https://github.com/ollama/ollama/issues/3041

Hi there! I am gonna let devices access ollama through LAN therefore I set the OLLAMA_HOST=0.0.0.0
When I restart ollama, the models I pulled before disappeared, I don't know whether it is a bug or something else.
In addition, I think we need a 'restart' command to restart the server.
Thanks for help in advance.
Ollama:0.1.28
My OS info: Ubuntu 23.04 Linux-6.2.0-39-generic

Are the models becoming not available via the network or via the console?

Ollama can be restarted with systemctl restart ollama.service

Hello @aosan , the models are not shown from the ollama list, and when I calling the /generate api, it returns 404.
Thanks for the restart command, but it seems have no effect with the OLLAMA_HOST set. The host still stay at 127.0.0.1, when I set the OLLAMA_HOST to 0.0.0.0 and using systemctl restart ollama.service to restart ollama.

The host turns to "[::]" when I stop ollama by using systemctl stop ollama and start it using ollama serve.

are you defining OLLAMA_HOST=0.0.0.0 in /etc/systemd/system/ollama.service ?

After you try to put the config in ollama.service, one way to confirm it listens on 0.0.0.0 on IPv4 is to check it with:

sudo netstat -tapen | grep ollama

and it should show you something like:

tcp 0 0 0.0.0.0:11434 0.0.0.0:* LISTEN 968 291784 35171/ollama

If you see ::, it might be IPv6, where the same netstat command would show you something like this:

tcp6 0 0 ::1:11434 :::* LISTEN 0 14221 2114/ollama

I hope you can get it working, these configuration fogs can be frustrating.

Hi there, when changing OLLAMA_HOST on Linux it's important to do this in the systemd service, since Ollama runs as it's own process and user in the system. You can do that by following this guide. Let me know if that helps!
