jslib from WebSocket doesn't receive data

I'm trying to use the [websocket package][1] unity provides from the asset store to connect to my server from WebGL, but for some reason I cannot receive messages; only send them when testing in the browers , but works fine in the editor. I've found the reason it works in the editor is because in all other platforms except WebGL, it uses websocket-sharp.dll, and in WebGL it replaces the dll for a [jslib][2]. The client [WebSocket wrapper][3] The client [echo script][4] The [server code][5] Any help appreciated, thanks!
