.net core nginx hosting sockets doesn't allow http post

Question

I am trying to make a website that would have http functions including http post functions, and also web sockets (such as signalR). I am trying to host this website on an ubuntu

Answer 1

Here is my configuration for .Net Core API with nginx:

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_http_version 1.1;
    proxy_set_header X-NginX-Proxy true;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_cache_bypass $http_upgrade;
    proxy_redirect off;
    proxy_set_header X-Forwarded-Proto $scheme;

The main idea are remove these lines (if you have)

proxy_set_header Connection "upgrade";
proxy_set_header Connection keep-alive;

and insert this line in your configuration

proxy_set_header Connection $http_connection;

Hope it helps.
