As mentioned here: Http/2 WebSockets support

.NET 7 introduced Websockets over HTTP/2 support for Kestrel, the SignalR JavaScript client, and SignalR with Blazor WebAssembly.

Note:

HTTP/2 WebSockets use CONNECT requests rather than GET, so your own routes and controllers may need updating.

Which means that you have to change [HttpGet("/path")] by [Route("/path")] as mentioned here: Add HTTP/2 WebSockets support for existing controllers

But now my socket doesn’t connect anymore.

It also says:

Chrome and Edge have HTTP/2 WebSockets enabled by default, and you can enable it in FireFox on the about:config page with the network.http.spdy.websockets flag.

But I’m using Chrome and it seems that it is not enabled by default.

• How can I verify if it’s enabled (and Websocket uses CONNECT instead of GET)?
• Or even better, how can I fix my problem (my code is a copy/paste from the WebSocketController provided in the documentation)?
