Visual Studio 2015 - Unable to connect to developement Web Server (IIS)

When I use as binding protocol localhost, I can connect localy without any kind of problem, but when changing it to my local IP address, I can access it momentarily, and then, when Visual Studio tries to connect to it, it just crashes and it unaccesible.

I have introduced these rules:

netsh http add urlacl url=http://ift.tt/2icvBzO user=todos
netsh advfirewall firewall add rule name="IISExpressWeb" dir=in protocol=tcp localport=9999 profile=private remoteip=localsubnet action=allow

And I can even connect it from other computer in the LAN, but as I said: I can just access it for 30 seconds, then, Visual Studio throws the error: Unable to connect to developement Web Server and I have to press the Run button to access it for another 30 seconds
