Hey @Peter-Jan_Bosch,
Welcome back to Community and thank you for reaching out to us with your question! We’d be happy to help with this.
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Once we have a clear picture of your setup we’ll begin troubleshooting this issue and get this cleared up.
In the meantime, please use the BluOS app to ensure that your Bluesound devices are running the latest firmware.
