Nest Doorbell (Wired) Randomly Stopped Working

My Nest Doorbell (wired) has been connected for at least 1.5 years, but as the previous owner installed it I'm not sure how long it has been installed.  It randomly stopped working the other day, but was able to power on when I plugged it into a USB charger. 

The doorbell draws current from a GFCI outlet in a bathroom which goes into a transformer in an adjacent closet.  When the camera first went out I noticed that the GFCI outlet had tripped so I reset it.  This caused a very short doorbell chime followed by some serious buzzing from the chime box.  The doorbell was still nonresponsive at this point.

I used a multi meter to test the voltage coming from the transformer, going into the chime box, and ultimately the wires that attach to the doorbell and all seemed to be acceptable at ~18 volts. 

The buzzing mechanical chime box seems consistent with an older doorbell held down for a length of time.  I rewired the Nest doorbell to see if it was shorting somewhere, but there was no difference.  What gives?

TL;DR, Nest Doorbell (wired) seems to be shorting and I'm not sure how to fix it.

Solved: one of the wires connected to the doorbell became weakened and eventually broke. This was likely making a bad connection.

Just happened to mine too. Hoping to have it replaced

Check to make sure the wires haven't become weakened or brittle. That ended up being my issue.
