Hi perfectlisir,

perfectlisir

"KeepAliveTimeout":20.0,"DisconnectTimeout":30.0,"ConnectionTimeout":110.0,"TryWebSockets":true,"ProtocolVersion":"1.3"

According to the log, I just find you set "TryWebSockets":true", but it seems that either your client or server do not support WebSocket, it uses Server Sent Events as transport.

Your client seems lost the connection and re-establish the connection after it connected, you can try to broadcast message to all clients and check if only that reconnected client misses the message.

Besides, please start connection without passing value via QueryString and check if your project works fine (maybe other factor cause the issue).

Hi  Fei Han,

Thank you very much for your answer!<o:p></o:p>

The iOS side USES WebSocket transmission mode to chat normally, and the server supports WebSocket. "TryWebSockets":true" is SignalR set at the bottom, and I can't set it.At present, my project (Android) can run normally, Server actively push the client can receive the news, but the transport is the Server Sent the Event, the Server push regularly, consuming resources, so I want to ask you is there any method can solve, will transport by ServerSentEvent change for WebSocket, look forward to your comment!

With Regards,

Hi perfectlisir,<o:p></o:p>

Your server supports WebSocket, and if you’re sure that the client also supports WebSocket, you can try to specify transport. <o:p></o:p>

$.connection.hub.start( { transport: 'webSockets' });
