Can't Control Google speakers through Google Home

[MrChris]

I've spent about 2 weeks trying to figure this out, and I'm stumped.

I used to be able to control the volume of my Google Mini's in the Google Home app.  Two weeks ago, I tried casting to one of my Google Mini's and noticed none of them showed up in any of my music apps. I opened Google Home, and when I tap on any mini to control the volume or cast, I get the sad ice cream cone image with "Not Available. Can't see <speaker> on this Wi-Fi network."

Here's what works and doesn't:

1. The Mini's work fine. I can ask them to play from any music source and they play. They can control all my smart devices.

2. Both the Mini's and my phone are on the same SSID and the same 5GHz band.

3. My wife's phone (Google Pixel 8a) and our tablet (Lenovo) can control the mini's just fine. They both can cast to them and control their volume in Home.

I just cannot figure out why my phone can't cast to my Mini's or control their volume from within Home. My phone is a Samsung Galaxy S24+ with the latest updates.

1. I'm not on any VPN.

2. I've removed all my ad-blocking apps.

3. I can see all the devices on the wireless network with a network scanner

4. I can control every smart device through Home

5. I can cast to my Roku TV fine.

6. I've tried resetting my wireless/bluetooth settings with no luck

7. I've re-installed Google Home

8. I've rebooted my phone, toggled airplane mode, turned off mobile data

9. I just got 2 new Google Nest Audios and set them up with the Lenovo tablet. My Samsung phone still cannot control them when I tap on their tile in Home.

Does anybody have any other suggestions to try outside of a factory reset of my phone?

Hi MrChris,

Thank you for posting in the community. I understand that you try to cast your nest mini but they don't show up on any of the music apps.

Before, I begin with the troubleshooting, I'd like to ask you a few questions below:

• Is the router within 15 to 20 ft (4 to 5 m) of the speaker?

• What kind of Nest mini generation do you have? 
• Were you able to set up the device on your network and cast from other supported apps?
• May I know if your wife is the owner of the account? 

Keep me posted

Best regards.

Rusell,

1. The closest speaker is around 10ft from the nearest access point.
2. They are a mix of Google Nest Mini Gen 2 and Google Nest Audio.
3. I was only able to set up the new Nest Audio's from a device that wasn't my phone.  The Nest Mini's were originally set up from a phone that I no longer have.  I cannot cast to any speaker from any app on my Samsung S24+.  My wife's Pixel 8a and our Lenovo tablet can cast to the speakers without issue.
4. My wife and I are both set as Manager on the home

Hi MrChris,

Thank you for your response. As you mentioned, the inconvenience only occurs when using a Samsung mobile device. Since your Nest Mini works with other devices, we recommend contacting Samsung support for further assistance. We are sorry that you are facing this inconvenience.

If you have any additional questions, please feel free to reach out.

Best regards,

Rusell.

Just wanted to come back and provide the solution that I found:

On my wireless setup, I had to enable mDNS support on the WLAN and make sure mDNS support was enabled on the interface.

I still have no idea why other wireless devices worked fine and my Samsung phone required these changes.
