How to start Hub connection on signalR with Java-client with app server based Azure signalR Service?

Question

I have followed above signalR architecture and we have used ASP.NET SignalR, And I am trying to connect from JAVA-client,

Step 1 : IF i do negotiate request to app server than i am getting following response strong text

{
    "ProtocolVersion":"2.0",
    "RedirectUrl":"https://test.service.signalr.net/aspnetclient",
    "AccessToken":"<a typical JWT token>"
} 

but when i am trying to connect azure signalr service from java-client than i am getting following error on Hubconnection.start().get().

**

Error:microsoft.aspnet.signalR.client.transport.NegotiationException

** Note: I have not used ASP.NET CORE SignalR

APP server is already allowed websokets,

Can you help us to identify exact java client to connect "ASP.NET SignalR" Azure service
