No response when using ollama behind an nginx proxy

[rwatts3]

I am running ollama on my Google compute instance behind an nginx proxy. I can navigate to the endpoint and confirm /api/tags returns a response as well as other endpoints such as /api/version.

Unfortunately when I add my endpoint via enchanted's settings, I can send a chat, but I never receive a response. I also confirmed that the request is received by ollama via the logs on the server.

Hi @rwatts3 if you could post a minimum set of instructions to reproduce your environment I'd be happy to go and debug the issue.

Hello,
I have the same issue as @rwatts3. I can't tell his setup, however, I can explain mine so it might help you @AugustDev !

Here is my nginx reverse proxy configuration for exposing the API :

upstream ollama {
    server 127.0.0.1:11434;
}

server {
    listen 80;
    listen 443 ssl http2;

    ssl_protocols   TLSv1.3;
    ssl_ciphers     ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
    ssl_prefer_server_ciphers off;

    if ($scheme = http) {
        return 301 https://$host$request_uri;
    }

    location /api/ { # I've tried with and without / at the end of api, but same result
        proxy_pass http://ollama;
        proxy_redirect off;
        proxy_set_header Host       localhost:11434;
    }
}

I'm using a self-signed certificate, and the endpoint configured inside your app is https://<IP>/api
When going to https://<IP>/api/tags from my computer for example, it is returning a result.

Maybe the issue is because I'm using self-signed certificates ?

Well, it seems that not, since I've just disabled https and I'm able to get an answer from http://<IP>/api/tags from my computer.
Inside your app, I then tried these URL without anything working :

• http://<IP>/api
• http://<IP>:80/api
• <IP>/api
• <IP>:80/api

Between each changes, I'm restarting the app as well.
The app is running on iOS 17.4.1
Echanted version : 1.6.4 (I'm trusting the version number shown by the AppStore)
Ollama version : 0.1.32

If you need more informations don't hesitate to ask, will try to do my best !
