💡 Refused = nothing listening on that interface; timeout = something dropping packets.

问题
curl http://localhost:11434 works, but the LAN IP returns Connection refused (or times out from another PC).
报错原文（已脱敏/规范化）
curl: (7) Failed to connect to <lan-ip> port 11434: Connection refused
如何确认是这个问题
lsof -i :11434 shows 127.0.0.1:11434 LISTEN only.
根因
Ollama binds 127.0.0.1:11434 by default. A timeout after the bind is fixed usually means a firewall dropping packets.
修复步骤
- Set OLLAMA_HOST=0.0.0.0:11434 the way your platform needs:
- Linux systemd:
Environment="OLLAMA_HOST=0.0.0.0:11434"under [Service], thensystemctl daemon-reloadand restart Ollama. - macOS:
launchctl setenvno longer works for the Ollama app since 0.3.14 (ollama#7331). Use the app's network exposure setting, or add OLLAMA_HOST to the Homebrew service plist, or runOLLAMA_HOST=0.0.0.0:11434 ollama serve. - Open TCP 11434 in the firewall.
- For browser clients also set OLLAMA_ORIGINS.
如何验证
lsof -i :11434 shows *:11434 LISTEN and curl http://<lan-ip>:11434 returns "Ollama is running".
试过没用的办法
macOS: launchctl setenv OLLAMA_HOST ... is ignored by the Ollama app since 0.3.14 (ollama#7331).
风险提示
(Our own safety note, not from the sources) Ollama has no auth; expose it only on a trusted network or behind a reverse proxy.
