Hi, I've had several issues with our Wiki server running on Yosemite and server 5.0.15.
Last one is that movies (m4v) uploaded to a Wiki will not play when browsed from an iOS device. It works fine in Safari on a computer, but on iOS the play button gets strike through when you attempt to play. This even happens when I upload a movie from the IOS device.
Any ideas? Should any other ports be opened for this kind of streaming?
