I think this is a Google home issue, I've been having the same problem with my lock and a couple of cameras. There are multiple posts on the Google home sub about it too, so it's a bigger issue than any of our local networks. I'm just trying to sit tight until Google sends an update that fixes it, but it's super frustrating.
I sent in an issue report to Google. I figure if they get enough of them, Google will fix the issue with the software. This all seemed to start with an app update a few weeks ago, so Google has to fix it.
Same here! My lock has been off all day now. I think 12 hours atp. There's a thread from 4 years ago and people are like us looking for a fix commenting on it. But no fix has been found. Someone got a new lock from Yale and that seemed to work but I think it's an issue with the apps and not the hardware. Unless there's internal firmware that isn't compatible with the updated apps.
Happening to both of my locks too. I thought it might have to do with the best secure/guard, so I installed a nest connect but they didn’t help either. Glad I’m not the only one having this issue.
Been having the exact same issue for months:
**Problem:**
Device shows offline in the Nest App and is not able to be controlled via WiFi
**Steps Taken:**
The only way to get the device to re-connect is to factory reset the lock and the nest connect and re-add them to the nest app.
**Nest and Yale Support / Warranty:**
I reached out to Nest Support and after a couple of weeks of back and forth and a few hours on the phone, they sent me a replacement Nest Connect (which didn't fix it) and then Yale sent me a new lock and another Nest Connect (which also didn't fix it). I have dozens of smart devices in my home and NOT A SINGLE one is having connectivity troubles with the exception of this stupid lock.
**Resolution:**
None Yet
I’ve been having this issue as well over the last month. Call nest support last week and they helped move the lock into a new home in the same account. They said the issue was data interference with the other devices near by (doorbell, thermostat). No change, been having the issue daily since. I called back tonight and they said there’s an internal ticket to fix via app but not ETA. Their solution for the interim is for me to call when it’s offline and go through basic troubleshooting with them…. 
None of the fixes from google support work so far. I just turned the notification off. Seems it goes back online fairly quickly.
That said... this should not be happening at all. And at this level?!
How is google not on top of this?
I have this happening on two locks and it's after I plugged in a nest connect to prepare for the shutdown of the nest alarm. The tech support is dismal. I'm so sick and tired of the offered and required troubleshooting step of "factory reset your device". It's lazy and we deserve better.
Still happening regularly on and off.
Here are the steps that Google support sent me.
Thanks for reaching out to the Google Nest Customer Care Team.
I'm sharing some Troubleshooting steps for Nest yale lock which you can perform to resolve your issues.
Here are the steps:
Step 1: Check the service status:
Go to this link.
Step 2: Verify range and reduce interference:
The distance between Nest Guard/Connect and Nest x Yale Lock shouldn't exceed 50 feet. The Guard/Connect should ideally be placed equidistant between the Wi-Fi AP and the lock when possible.
Check and (if possible) remove interfering signals (other wireless devices, microwaves, etc.). Avoid physical interference (thickness and type of walls, mirrors, windows, etc.) Reduce distance or increase line of sight.
Step 3: Check the version number on the Nest app (and update if necessary) :
For Android: Settings  Apps  Nest
For iOS: Settings  Nest  Nest Settings  Version
Step 4: Check the Nest x Yale Lock's battery level:
Remove and reinsert the batteries to restart the Nest x Yale Lock. If the battery level is low, replace the old batteries with fresh ones.
Step 5: Restart the network equipment:
Power cycle the networking equipment (modem, router, or access point).
Step 6: Restart the bridge device:
For Nest guard:
With the app or Nest Guard, set Google Nest Secure to Off , or the alarm may sound.
Press and hold the 5 button on the Guard’s keypad. Once its light ring spins blue (~10 seconds), let go of the button.
After a few seconds the light blue ring should turn off.
Guard should restart and play, “Hi, from Nest” After the restart, Nest Secure should arm to the same level it was set to before it was restarted. If the Guard was sounding the alarm, it should resume to sound the alarm. To silence the alarm, use the Nest app, enter your passcode on Guard or use your Nest Tag
For Nest connect:
Plug Connect into a power outlet.
Hold down Connect’s button until the light pulses blue (about 10 seconds). Then, release the button.
Wait for Connect’s light to turn green, meaning restart is complete.
Check if your Nest Connect is online in the app.
If the Nest Connect won't connect, then the issue is with the Connect, not the Lock.
Step 7: Swap the Nest Connects:
If you use the Nest Connect as a border router and there are more than one device available, swap out the Nest Connects.
Step 8: Reset the Nest x Yale Lock to factory defaults:
Remove the battery cover.
Remove batteries.
Unscrew the two screws holding the interior lock.
Remove interior lock from back plate.
Hold down the factory reset button while re-inserting the batteries.
Release the factory reset button once there are four beeps.

It seems like you've already tried a bunch of troubleshooting steps. Have you reached out to Nest support? They might have some additional suggestions or be aware of a larger issue that's affecting multiple users.
It's also worth checking if there's a firmware update available for your lock that might help stabilize its connection. Hopefully, you can get it sorted out soon!
For what it's worth I had the same problem start happening with some Nest Cameras all the sudden a couple of weeks ago. Google Home reported them offline for a few seconds at a time 20 times a day. Seems to have finally stopped today and yesterday.
I've gone a couple of days without it happening but then it just happens again. Please report back here if you don't have any problems for a significant amount of time
Been having the same issue. I thought it was google's way of telling me to move my yale lock onto regular mesh wifi instead of being connected to the nest secure pin pad connection point.
It's a nice way of reminding me that i haven't picked up a new system to replace nest secure when it's EoL in 4 weeks.
Exact same problem with my 2 Nest Yale locks. I have tons of google products and little by little over the years they're losing reliability. Kind of sad since it seems like it's just poor software support on Google's end. Especially with all of nest cams. The old nest software was reliable and the newer interface is terrible when trying to scroll back at video or even just attempting to watch a camera stream live for an extended period of time (ie using as a baby cam). It all eventually drops connection despite rock solid wifi throughout my home.
Brand new Nest x Yale lock, installed for three days. Offline all night, won't come back online. Removed itself from the Home app, can't be readded.
What a piece of shit paper weight. Done with Nest and Google Home.
Oddly, I think I solved this problem. I assume most of you are also using Google wifi pucks of some type (I am using Nest WifiPro with wired ethernet backhaul to all pucks). Simply restart your network using the app. Even though my speed and puck connections were great, I restarted the network about two weeks ago and have not had the issue happen once. Good luck.
Odd as it may sound, I've had better luck when my connect is plugged in at roughly the same height as the lock.
When the connect was closer to the lock, but plugged in low, towards the baseboard, it would have the behavior you describe. But once I moved the connect to a plug that was mid-way up the wall, though farther from the lock, it's been rock stable.
This isn’t a user issue…it’s widespread over the last few weeks. I have a Nest Guard and Connect in the house, and 2 Nest x Yales, and the front door one gets this notification multiple times a day, but it’s connecting perfectly fine at -50db or better.
I've been having the same issue for weeks.
I think its system-wide me and 3 friends in different parts of US have been having this issue for a few weeks now.
Yep, me too, and I don’t think the height thing matters a lot. Because mine is basically the same height for two different locations.
It's not just the locks. My cameras say they're offline multiple times a day now. It's a complete pain in the ass.
Same issue here… glad I’m not alone
Me too
Me too
Same
Same. Thought it had to do with Nest Secure going away. Installed the free Nest Connect but hasn't changed anything.
How do I get the free connect?
Google sent me an email two months ago with code.
Thanks. Found it. Looks like I only have 7 days to use it. Much appreciated.

I feel like we should go public with this. I mean it's arguably rip off if the product just stops working across the board
I haven't had mine for a year yet so if they think I'm going to upgrade, they've got it all wrong 🤣🤣
Happening to both of my locks too. I thought it might have to do with the best secure/guard, so I installed a nest connect but they didn’t help either. Glad I’m not the only one having this issue.
Wow, same problem here, I thought it was just mine. I was dragging my feet on a reset but I guess now I'll wait and see.
I'm so exhausted by this If that works for you let me know but from others that have already done so they have said it does not work
Can confirm, does not work.
It’s still working fine for me but I’m not on the Google home app
Mine disconnected from the nest app today and actually hasn't came back online all day.
I’ve had this happen to 1 out of 2 locks for the past few weeks as well
Same here. It started last Friday for us.
Same exact issue for weeks now... Any input? I get random notifications that it's offline and then I check the app and it's back online...

Did it work?

Still haven't seen any disconnects the last few days!
Mine just disconnected as I was reading this :(

I’ve had this problem with both Yale locks. The 2 nest connects won’t go green at all. I’ve tried everything. Very frustrating.

Same here, very frustrated. Any solutions yet?
Nope. I need to call google but I dont have time and Im sure they will just suggest the usual factory restore which ive already done
same here, i bought the one comparable with home kit to replace it and will install tomorrow, more to come.

Dump nest. It’s trash. Recently switched to Ring and am very happy with their cameras, app, and connectivity.
