None of my minis will tune in channel that comes in fine on roamio

So, this morning i noticed that i can't tune in to chanel 1915 on my mini. When i tune to it i just get a black screen. If i change away from it and back to it i get a black screen with the blue spinning circle and the mini is locked up and completely unresponsive until I either unplug power or the coax until it says it's lost connection. This happens on all 3 of my minis. The channel tunes in fine on the roamio. I've restarted the minis and the roamio, but the issue persists. Any insights or suggestions are welcomed. Thanks.
