Original GitHub issue: https://github.com/open-webui/open-webui/issues/261

I just want to proxy ollama-webui by nginx.
And there is the config


server
{
	listen 3389;
	server_name ai.myai.com;

	location /
	{

		proxy_redirect off;
		proxy_pass http://127.0.0.1:8082;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "upgrade";
		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_next_upstream off;


	}
}

Also, I started the ollama-webui in docker.

docker run -d -p 8082:8080 --add-host=host.docker.internal:host-gateway --name ollama-webui --restart always ghcr.io/ollama-webui/ollama-webui:main

In fact, When I started ollama-webui in the 3389 port, everything was ok. But when I proxy it by nginx, there is a 403 Forbidden error.

Do anyone know what the problems are?

Have you tried doing it with this Apache proxy example?

@oliverbob

OK, I solve this problem.

The blew config of the Nginx proxy is ok.

server {
    listen 3389;
    server_name ai.myai.com;

    location / {
      proxy_pass http://127.0.0.1:8082;

    }

    location /ollama/api {
      proxy_buffering off;
      proxy_set_header Origin '';
      proxy_set_header Referer '';
      proxy_pass http://127.0.0.1:11434/api;

    }

    location /api/v1 {
     proxy_pass http://127.0.0.1:8082/api/v1;
    }
}

And there two lines are very important

      proxy_set_header Origin '';
      proxy_set_header Referer '';

But I have no idea why this happened. And I thought this was not Ollama-webui's problem. Maybe it's ollama server's problem.

Because the 403 error is generated by Ollama Server but not Ollama-webui.

Thanks. I appreciate your help.
