I have my main site successfully running with https proxy to my localhost:5000.

I need to also route websocket traffic from mydomain:4000 to localhost:4001.

I can’t get this to work with nginx. I don’t get any build errors, but my websocket can’t connect.

Here is my sites-default file:

Default server configuration

server { listen 80; listen [::]:80 default_server ipv6only=on; return 301 https://$host$request_uri; }

server{ listen 4000; listen [::]:4000; server_name app.mydomain.com;

location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass https://localhost:4001/; proxy_set_header Host $http_host; proxy_cache_bypass $http_upgrade; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection “upgrade”; proxy_set_header Host $host; }

}

HTTPS — proxy all requests to the Node app

server { # Enable HTTP/2 listen 443 ssl http2; listen [::]:443 ssl http2; server_name app.mydomain.com;

# Use the Let’s Encrypt certificates
ssl_certificate /etc/letsencrypt/live/app.mydomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/app.mydomain.com/privkey.pem;

Include the SSL configuration from cipherli.st

include snippets/ssl-params.conf;

location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;
    proxy_pass https://localhost:5000/;
    proxy_ssl_session_reuse off;
    proxy_set_header Host $http_host;
    proxy_cache_bypass $http_upgrade;
    proxy_redirect off;
    proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "upgrade";
proxy_set_header Host $host;

} }
