You are not allowed to join this debug session

Hi community,

I'm trying to start the debug but I have this error message "You are not allowed to join this debug session". 

I suspect that firewall is blocking me, so my question is: debug uses any specific port or it uses 80?

Thanks in advance.

Hi Nuno,

You didn't specify what you are trying to debug, and while I imagine it is a web application, I'll let here first a link for troubleshooting Mobile Debugging problems (more common):

And for Web, you ocan check this topic:

Hope this helps.
