Reverse proxying https://example.net to http://localhost:8080 works fine with Caddy reverse_proxy.
Reverse proxying ws://example.net to ws://localhost:8080 works also fine with Caddy reverse proxy.
But I do not know how to reverse proxy wss://example.net to ws://localhost:8080 with Caddy reversy proxy for enabling web sockets.

I have tried out the https://spring.io/guides/gs/messaging-stomp-websocket tutorial. It tells, how to use websockets with Spring Boot.
When I try it with localhost:8080, everything is fine.
When I run it on a webserver as localhost:8080, I have configured Caddy
example.net:80 {
reverse_proxy localhost:8080
}
and I have configured app.js to the more generic brokerUrl '/gs-guide-websocket' (without the ws://localhost:8080).
it also works fine als http://example.net without TLS.
Now I tried to enable TLS and so I configured Caddy to
example.net {
reverse_proxy localhost:8080
}
I want have it locally running via http://localhost:8080 using Caddy to bring this out to https://example.net .
With normal websites (without websockets), this works fine.
So when I try, the website https://example.net itself is loaded.
But the connection to Websocket fails:
WebSocket connection to 'wss://example.net/gs-guide-websocket' failed.
I want to achieve that wss://example.net/gs-guide-websocket is proxied to ws://localhost:8080/gs-guide-websocket.
How to make it working?
