Frontend Stuck on "Connecting…" via NGINX Reverse Proxy

[NakshtraYadav]

When running Cloud Torrent v0.9.4 on my AWS Ubuntu server with NGINX reverse proxy, the web UI at my domain gets stuck showing "Connecting…" indefinitely.

All frontend assets (HTML, CSS, JS) load correctly, and the backend service (cloud-torrent) is actively running on port 3000.

🔎 Observations
All static assets (JS, CSS, templates) return HTTP 200 successfully.

Logs show the frontend requesting /sync, but no torrent data appears.

No JavaScript errors in browser console.

Service is accessible at 127.0.0.1:3000, and NGINX forwards correctly to it.

The issue only occurs when accessing via the domain through NGINX.

When accessing localhost:3000 directly, it works perfectly.

🔄 Attempted Fixes
Tried launching with --auth=false, --log, --host=0.0.0.0, etc.

Verified NGINX config correctly proxies / to http://localhost:3000.

Ensured no firewall or network issue is blocking requests.

Tested basic HTML page through same NGINX → works.

works alright with just accessing via browser on my public ip (aws ubuntu)

on my domain

you can see the sync in the network tab is pending

it's NGINX Config issue

Go to nginx Config file and in
`
location / {
proxy_pass http://localhost:3000;
# Required for SSE
proxy_http_version 1.1;
proxy_set_header Connection "";

# Disable buffering
proxy_buffering off;
proxy_cache off;

# Increase timeouts
proxy_read_timeout 1h;
proxy_send_timeout 1h;

# Don't change transfer encoding
chunked_transfer_encoding off;`

after that
sudo systemctl daemon-reload
sudo systemctl reload nginx
