[Plugin] Socket.io Client

Hi, this plugin need some any extra install?
Installed from marketplace, tryed the client sample, but not connetcting to server, don’t get any error.
Tryed from pc and android too. The server is run by another phone (work because can connect, send data with another client app).
Ip and port is good.
Created exe, added to firewall exception, still not work.
Packaged to android phone (android 7), not connect to the server.
4.20.3 UE version.

Any idea?
