Cannot reset or run safety check on Nest Protect

[bwali]

A few days ago I had a carbon monoxide alert from the protect in my garage.  The levels reduced after opening the garage doors, but all of my Protects are pulsing yellow every 5 seconds.  I have tried to run a safety check via the app, but it will not start.  I have tried to perform a reset, but after pressing and holding the button, the device starts to say its version number, but is cut-off before it can complete and instead says “silenced” and returns to the yellow pulse every 5 seconds.  This is the behavior on all of the protects in the house.  Google support was not able to resolve.  The Gen 2 protects were purchased and installed approximately 6 months ago.

Problem solved.  I was not able to isolate a single protect, but did continue to attempt to reset different protects.  I also have a Nest mesh wifi, and sequentially reset each end point.  Apparently that forced the protects to reconnect and that resolved the issue.
