Connection error occurred with socket.io-client-java

[jgodstime]

I have implemented socket using this library for my backend, i have tested with a Js client i built, and it worked. But refuse to connect for my Android client, he is using this library for the java client https://github.com/socketio/socket.io-client-java

This is the error he is getting

E/ChatFragment$onConnectErrorEmitter: Connection error occurred 
    
     [Ljava.lang.Object;@afbba9b

please any idea will be appreciated ASAP. Thanks.
