Original GitHub issue: https://github.com/ollama/ollama/issues/12053

What is the issue?

Since upgrading from v0.11.4 to v0.11.5 (and also v0.11.6), ollama serve only listens on localhost/127.0.0.1.
In v0.11.4 it listened on all interfaces (0.0.0.0), so I could connect via my LAN IP (e.g. 10.0.1.120).
Now external connections from other devices on the network fail.

Steps to Reproduce:

Install Ollama v0.11.5 or v0.11.6

Run:

ollama serve

or even with:

OLLAMA_HOST=0.0.0.0:11434 ollama serve

From another machine, try:

curl http://10.0.1.120:11434/api/tags

Connection refused.

Expected Behavior:
Server should bind to all interfaces (or at least respect OLLAMA_HOST=0.0.0.0) and allow access via LAN IP.

Actual Behavior:

v0.11.5 / v0.11.6 → only accessible via 127.0.0.1

v0.11.4 → accessible via LAN IP (10.0.1.120)

Environment:

OS: MacOS 15.6.1

Architecture: arm64 (M1)

GPU/CPU setup: M1 Max

Notes:
Explicitly setting OLLAMA_HOST=0.0.0.0:11434 does not help in v0.11.5/0.11.6.

This looks like a regression introduced in v0.11.5 and 0.11.6.
