Nest mini speaker group not working

[JoshR9289]

I have a few nest minis and up until recently I was able to create a speaker group and cast audio to all of them but now one of the speakers won't connect. It shows in the group not no music will be playing unless I connect to it individually but then I can't play through the group. Everything is up to date and all on the same mesh network

Hi JoshR9289,

Thanks for posting to our community.

I’m sorry to hear that one of your Google Nest speakers has stopped playing music as part of the speaker group you created as it used to. Thank you for letting us know that the device is working fine individually, but the failure happens when you try to add it to your speaker group. No worries; it is my pleasure to assist you with this inconvenience.

Before we get started with further troubleshooting, let me ask you some important questions:

How far from the router is the Google Nest speaker that is disconnected from the speaker group?

Could you please double-check that the disconnecting Google Nest speaker is connected to the same WiFi network as the other devices in the speaker group?

When you open the Google Home app, do your speakers remain online or go offline?

Can you describe the status of the 4 LED lights of the speaker that are disconnected? (Please refer to this article for reference: Google Nest and Google Home device LED lights.)

Have you tried connecting the Google Nest speaker to a different power source?

Have there been any recent changes to your home environment, or any changes in Wi-Fi network or recent outages?

Have you tried to reboot the Google Nest speaker that is disconnecting?

What's the Google Nest speaker  firmware version?

Thank you for your time and attention. I look forward to your response.

Best regards,

Virna
