While trying to move Turtle to UppHub, I have noticed it does not work Smile (I will gladly provide you commit rights there as soon as I find out your github username...)

The reason seems to be that after uploading html, we try to establish WebSocket connection over the same port. Unfortunately, at the same time browser tries to fetch favicon, which gets cought by WebSocket and connection is terminated because that is not the correct websocket request.

Have you noticed this issue?

Trying to remedy that by moving websocket communication to another port...
