JRiver help

Ok gents, I have been using Jriver for a while, but recently the software isn't discovering my DLNA players. It used to identify all 3 of my fire tv's, WiFi music streamer, avr, and bluray player. Now it no longer sees the fire tv's, and the music streamer is intermittent. When it does connect to the WiFi music streamer it will only work if I use its analog out. However if I use the airfoil software the digital out works as it should. Suggestions?
Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant
