The problem is in the file: GUI/main.html
Review this link.
It talks about how to be able to obtain security permits to send the message to the server.
This is necessary, because I have tried to establish the connection to the server and it gives me information saying that I do not have permission to establish this connection.
It is because browsers, for security reasons deny those permits and you have to do it in a concrete way, as explained in the link above.
Try to readjust it using what is mentioned in that link.
