Hello scot-e-dog,
welcome to Rune Audio.
Previously, every so often, I couldn't connect to Runeaudio with the browser on another computer connected to my network. A reboot of the RPi would always fix this.
This is strange and shouldn't happen at all.
Do you also use the Android App?
Is it possible to
ping the Pi (IP-address)?
Please check the IP address on your 7" TFT (MENU->Network).
