Error: Cannot find web socket backend

Hello

I’m creating a website for farm management. I’m running a Asp Net Web API on CyberPanel. I’ve done it following this article: Publish & Run ASP.Net on CyberPanel / Linux – Blog of Viov

The problem is I’m using a technology called SignalR. The SignalR is basically a top level abstract layer to simply web socket (it also include other functionalities but it don’t matter now). Everything was going as expected on the development environment but when I deploy the application and host the Asp Net on Cyberpanel the Web socket stops working.

The Error Log prints this error:

2023-05-24 09:26:32.085918 [INFO] [18351] [187.74.137.142:46278#api.milksolve.com.br] Cannot find web socket backend. URI: [/fazendahub]

The client says that the Websocket didn’t send the handshake, so the Websocket definitely is not working. I checked the access log and there I confirmed that the Signalr protocol is broking on the web socket connection. Anyone has a solution?

My OS: CentOS 7 64bit

After days of research I created my own solution and its available on stackoverflow: asp.net - Error on Asp Net SignalR hosted on Cyberpanel - Stack Overflow
