Just checking in to see if you still need assistance with this issue. If so, please let me know and I would love to look into this further for you!
P.S Thanks for all of your help, Ashepherdson!
I am also having the same issue with the Yale lock. We recently had a Wifi Router replaced and we've connected the Nest thermostats and Nest Connect, but the Yale Lock will not connect to Nest Connect. We've done every step outlined in the article, but the Yale Lock still won't connect.
I can connect the nest connect but the nest take lock will not connect. During the process I have to press the physical button until I see the "blue light'' which means the lock is ready to be paired. My issue is that never happens even if I press the button during 15 or 20 seconds.
I don't know if I am clear.
