Yes, for all demos.
I can run them in the IDE only.
I've stopped ALL the possible (antivirus, firewall, Apache, IIS7).
This PC runs well with Apache (I've some web sites on different ports) and with IIS7 also (I've a Web site in ASP listening on port 8081) with MySQL on port 3306.
I've also added a stupid rule on my router opening the 8077 port...
Nothing to do: always Can't connect to localhost:8077.
:( :(
