我有两台服务器，一台是GPU服务器，另一台是CPU服务器；

我在GPU服务器上安装了Ollama，然后通过命令映射端口到CPU服务器：

ssh -CNg -L 0.0.0.0:11434:127.0.0.1:11434 root@connect.westb.seetacloud.com -p 34016

映射成功了在Cpu服务器通过curl http://127.0.0.1:11434 可以看到响应内容：

Ollama is running

内网IP，也可以看到内容：

curl http://192.168.0.137:11434

我现在想通过nginx 代理下，把ollama服务开放到公网

server {

listen 80;

server_name ollama.guifanhua.com;

location / {

proxy_pass http://127.0.0.1:11434;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Forwarded-Proto $scheme;

}

域名解析是没问题的，但是公网无论如何都不能代理成功，在公网访问：http://ollama.guifanhua.com的时候报错：

找不到 ollama.guifanhua.com 的网页

找不到与以下网址对应的网页：http://ollama.guifanhua.com/
