One of the most common Support issues is when the CasaTunesX App is not able to communicate with, or will not connect to, the CasaTunes music server.

This can be caused by one or more of the following issues:

1. The CasaTunesX App on your Android or iOS device does not have access to your local network
2. The Android or iOS device is not connected to the same network segment as the CasaTunes music server
3. The network is blocking multicast traffic which is used by the CasaTunesX App to discover your CasaTunes music server
4. The music server is not powered on, not connected to the network, or the music server network connection is not working
5. There is a hardware problem with your music server

Download the latest CasaTunesX App

If you are not using the CasaTunesX App, then please download the CasaTunesX from the appropriate store. The CasaTunesX App is the recommended App for CasaTunes.

Manually restart your CasaTunes music server

If after you have downloaded the CasaTunesX App you still cannot connect to your CasaTunes music server, then the first step you should take is to manually restart your music server following these steps.

Check your Android or Apple device is configured properly

1. Make sure your device is connected to your local WiFi
2. Make sure you have enabled the CasaTunesX App on your device access to use the local network
3. Make sure your device is not using a VPN connection

The mobile device and CasaTunes music server are not connected to the same network segment

If you have recently changed your network equipment, then:

1. Check to make sure that your mobile device and CasaTunes music server are connected to the same network
2. Check the music server is not configured with a local static IP

The network is blocking multicast traffic

Your CasaTunes music server uses multicast traffic to advertise it's presence. Because multicast traffic is usually not routed across subnets, it requires mobile devices to be on the same IP subnet as your CasaTunes music server. While this is common for most home networks, some homes and/or businesses have a more complicated network setup with multiple switches and access points which block the multicast traffic.

Common things to try:

1. IGMP snooping is enabled
2. Bonjour or uPnP is enabled on the switch

Music Server is not powered, or there is no network connection

Check the following:

1. The power cable is securely connected
2. The network cable is securely connected
3. The orange & green led's on the network switch port, connected to the CasaTunes music server, are flashing
4. The orange & green led's on the CasaTunes music server network port are flashing

If the orange & green led's in items 3 & 4 above are flashing, then most likely the CMOS BIOS battery needs to be replaced. You can send your music server back to CasaTunes to be refurbished, or you can follow these instructions to replace the CMOS BIOS battery.

If the orange & green led's on the server are not flashing then it is likely the server motherboard, network card, or other component has failed.

If you would like to diagnose the issue further, and you have an HDMI TV or monitor and a USB keyboard and mouse available, you can connect these to your CasaTunes music server, restart your music server, and capture any messages, if any, that are displayed on the screen when the music server is powered on.

Please contact CasaTunes Tech Support for further assistance.

In most cases, you will need to send the server back to CasaTunes to be refurbished for a nominal fee, or possibly have a local PC shop repair the server, if you are located outside of the USA.
