Google Assistant says “Sorry, I couldn't reach the home assistant.”

When I say “Ok Google, Open the Garage” the Garage opens, but it also says

Sorry, I couldn’t reach the home assistant.

Any idea on how to fix this?

Are you implying I didn’t use the search function? I did, and found nothing relevant.

There’s a number of threads about this issue, some of which I had commented on because I had the same issue.

Last I checked it was still unsolved. For me the issue only occurs randomly.

It’s only happening on my “garage door” device, which is dummy control which feeds the real device.

ETA: When I add the real device with pin, it’s still happening. Weird.
