What is the issue?

Can not make it listen on 0.0.0.0.
Anything I pass to OLLAMA_HOST results to listening on [::]:11434*

Relevant log output

 sudo systemctl stop ollama

[::] usually also means 0.0.0.0 - it's shorthand for "all interfaces". What does the following show:

sudo lsof -i :11434

What does the following return:

curl 127.0.0.1:11434/api/version

curl 127.0.0.1:11434/api/version
{"version":"0.9.0"}
and even
curl 172.17.0.1:11434/api/version
{"version":"0.9.0"}
hm.. so it should work for stuff running in Docker?
