Why can I use a certain program with QuickConnect?
In general, if a program doesn’t communicate through one of the methods listed on the permitted connections list, then it will be denied. For example, some audio streaming and video streaming sites will encounter problems with QuickConnect even though they’re presented through a web browser, because audio streams and video streams are often sent from different networking ports than regular web pages are. For more information on what is and is not permitted through QuickConnect, see QuickConnect and security. If you need to use a service which is blocked through QuickConnect, you can use the VPN server instead. The VPN server allows nearly all types of networking to succeed.
