Mine did too.  Installed 1 Apr 21 and it operated the heating system through June.  Ran AC through summer and then tested heat on 6 Oct.  That’s when n72 error noticed.  Read posts.   This is not unusual.  First it works, then it doesn’t.  Google never answers why, even when I proved Nest reports from period showing it in heating mode.  Good luck.  Recommend a $22 analog thermostat in the closet just in case.  I disposed of my old analogs two weeks prior.  Had to buy a new one.  You won’t get any real help from Support.  At one point, they blamed me for system not operating.

Solution is to abandon install and return your Nest for a full refund.  I have a problem happening right now.  Installed Nest Learning on 1 April.  Ran heat through May, then AC and Heat into June until we went to straight AC for summer.  Multizone heating system (forced hot water) with two Nest E's on other zones.  Testing heating system from Nest Learning on 6 Oct.  Taco box just kept clicking.  You will see other posts about this across the web.  Call heating company for PM b/c I assumed the problem was with boiler.  First thing tech said when he arrived was "you have a Nest thermostat, correct?".  He performed the same troubleshoot you did (W to Rh wire - triggered heat).  Notified Google and then sent me new baseplate (arrived last night and installed - no fix.  Same exact issues).  Contacted them again this morning and just went through 2 hours of painful chat troubleshooting with totally useless reps (Madison and then Enzo).  If you get them, stop the chat, pull the Nest out of your house and get another brand.  I'm done with having a teenager in their basement ask me if my house is powered and calling it support/troubleshooting.

Pay for some one to install that is what I had to do and now it works fine

$240 + 23 days with no heat + 5 days waiting for part that didn’t fix it + 2 more support sessions with no resolution + proposed solution costing $150-$200 and a few weeks more delay 

OR

$22 thermostat installed in 10 minutes that works

Unfortunately I did the first until realizing the later works just as well.

Thanks for the replies. One of my friends helped me out and now the thermostat works well.
