Gorilla websockets under nginx + ssl - how to do it?

Question

Nginx

There is a site that has nginx at the entrance, which proxies requests, depending on the url, either to the goroutine server with the application, or to wordpress.
The goroutine also has a websocket. The configuration worked quite well until the installation of ssl on nginx, after installation it does not function (which is generally expected).
Proxying is carried out as follows:

location = /ws {
            proxy_pass http://localhost:9000;
            proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
        }

Question: where to dig and where to edit - at the level of the nginx config, or do I need to get into the code on go?

Answer 1

What websocket address is used on the client? If you have https on the server, then the address must begin with wss://, not ws://
