Please update to the latest version and if the issue still persists provide clear steps to repeat.

Updated to the latest version，Draft_6455 It doesn't meet my needs，Unable to establish a connection with the other party's service, refuses to shake hands，Can you add a wechat or QQ chat

[Eucalyptus-fructicetorum]

I just tried the latest version and found that the URL can be escaped to get the information. Otherwise, or ENCODE will report an error

[marci4]

Well then the other party is not a websocket server.

Please provide steps to repeat!

[Eucalyptus-fructicetorum]

The other side is the server written by Node, will it produce some bad RSV errors, I read some such conclusions from the Internet，I will connect to the WebSocket service written by the other node normally, with the request path and request header information

[Eucalyptus-fructicetorum]

client = new WebSocketClient(new URI(wsUrl), new Draft_6455(), headerMap, 10000){}

That's not very helpful without access to the server or its source code (or at least more details).

One possibility is that the server is using socket.io, which is not compatible with direct WebSocket clients.
