Content in my channel is not showing up

Hi, I have a channel but some content that I have would not show up in some devices. I have 3 different Roku players, 1 at home 1 at my office and 1 more. At home I can see some content from my channel and that same content can not be seen in my office. My channel has content that does not show in either device although in my feeder (stream host) everything is set up correctly. Any thoughts? Thank you!
