Problem of websocket

hello! I want to get the sipml5 connected to my asterisk, I have asterisk 11.11.0 installed in a CentOS. I have also the latest version of sipml5 running in the latest vesrsion of chrome.
in the server part when I make in the chrome I have a response in the page and the websocket work correctly (I suppose) but this is not the case when I try to connect from the client side. In fact I’m getting this message from the debug of the sipml5 :

YOUR ARE USING DEBUG CODE. PLEASE USE CODE UNDER 'release' FOLDER or check for more information on how to amalgamate the code.

I don’t know where the problem is, I will be grateful if someone can help me, I’m really stack

Your browser has connectivity with the IP of the Asterisk?
Your browser are in the same LAN that Asterisk?
Your PBX firewall is allowing the websocket port?
Are you sure that Asterisk is listening and the websocket module loaded properly?

All of this questions can be resolved looking in the asterisk wiki or using google.

Thank you Mr navaismo! it was a problem of firewall :smile:
