I've been using the Mezzmo Android app on FireTV Stick and it's been excellent using Serviio as my PC-based server. Just today it is no longer detecting the Serviio server while still detecting Windows Media Player. Meanwhile Serviio continues to be detected by my iPad streaming app so it's still working. I've tried clearing the Mezzmo app's cache and details using the FireTV controls with no effect. Any suggestions?
