Hello Mark Strohmeyer,
Thanks for reaching out. That sounds like a very frustrating and unusual error. I would be more than happy to help find solution so that you can enjoy your speaker group. First, I have some questions regarding this situation:
  • Which Google speaker devices are you trying to connect? (model name, generation number)
  • Is this the first time you are making a speaker group?
  • Where is that error showing up? On the Google Home App?
  • Could you post a screenshot of that error message?
  • Are the speakers powering on and working normally besides this issue?
  • Have you tried any troubleshooting steps on the device itself? If so, what have you tried?
I look forward to your response, thanks!
