I am beginning to think there are some streaming format compatibility issues with some stations and the echo. for example, I just tried ozfm and the echo found it but says it is not available at this time. I tried it on my phone and on my computer and it worked fine. The following is from tunein regarding the same thing but with apple devices
The station you are trying to access is not available on your iOS device because it either does not broadcast in a compatible streaming format or it is currently inactive. Occasionally a station may become unavailable at the broadcaster's request, due to geographical restrictions, or otherwise. In most cases, TuneIn attempts to redirect you to a similar station to provide relevant content.
