SignalR no connection in ws mode

[mtlive]

I tried everything in documentation for using SignalR in websocket mode (ws scheme) but couldn't get it to work.
In our staging servers I get the "Handshake was canceled error" and in debug it takes so long that it switches out from ws.

Hi @mtlive !

I tried everything in documentation for using SignalR in websocket mode but couldn't get it to work.

Please note that we are not a consultancy team. I trust the community will assist you.

In our staging servers I get the "Handshake was canceled error" and in debug it takes so long that it switches out from ws.

Unfortunately, our repository lacks a robust sample, and the Websockets feature for SignalR is a complex functionality to implement. It would be more efficient if you could upload your solution to your account as a repository for us to review.

Regarding your settings JSON...
Why did you specify "ServiceDiscoveryProvider" section in global configuration?

Remove "DynamicRoutes" and "Aggregates" as well.
But the route definition looks good.

What's your "BaseUrl" in global configuration?
Did you setup Ocelot endpoint as WS one?

I recommend conducting a Bing search for ".NET websocket 'Handshake was canceled error'" now.
Unfortunately, I don't have time to spend on a solution that I can't see.

The issue was the wrong order of middleware.
