I have a Ruckuss wireless network, connected to HP Procurve switches, which are connected to a Watchguard XTM 535 firewall. None of the IPhone/IPad devices on our network are able to connect to any streaming video. Services such as Netflix and Youtube do not work. If I try to connect using the Youtube app I simply get an error message stating Playback error, Tap to retry. I have also tried to connecting to youtube through a web browsers and I just get spinning circles when I click on the video. I can take the same device home and connect to my wireless network there and have no issues. I have tested this with multiple IOS devices and can replicate the problem on all of them. I have also tested this with windows and android devices and do not have any problems. Any assistance will be appreciated.
