What device is it syncing with?

I don't think you are syncing the er7212 yet another device? That right?

It's adopted to a different controller before and that's why you have this error.

Update me if you have fixed it and the reason.

  @gerba I have this issue too - worked fine for ages, and suddenly it gives this error after any change to any aspect of the setup.

Very strange issue. I have a question about your config, so is your config now originally from the default config on the ER7212PC? I mean the very first default site and its config. Not imported from either an Omada Controller or another ER7212PC.

When did this start to happen? Any move like a firmware upgrade and this happens afterwards?

  @Clive_A No, the config is the original, not imported from another device.

 

It's been a while since it started happening, but I think it might have started when I updated the firmware on the SG2008P switch that is part of the setup (along with 3 x EAP615-wall units).

 

 

Since you introduced the switch, I gotta ask is this an error you see when you are trying to save/sync something to the switch? Or just tweak the parameters of the router and save them, you see the pop-up error?

I mean we need to figure out which one is the reason and focus on it.

  @Clive_A The error comes up when almost any setting is changed on the router, even when it doesn't strictly speaking involve the switch.

 

In addition, as of this morning, I now have multiple issues with DHCP, where multiple clients are not being issued with IP addresses at all, and others, which have DHCP reservations and IP-to-MAC bindings are randomly being assigned dynamic addresses from the DHCP pool, which is causing them to become invisible (they are PoE CCTV cameras, and when they receive a dynamic address, the NAS (NVR) cannot see them.

 

Unfortunately, this morning is also the time when I had to leave the premises for a week, which means I did not have time to troubleshoot the issue (other than a reboot of all TP-Link devices, which did not help), and also means that while away, I have no access to the CCTV, the heating controller, and the solar PV controller.

 

I'm finding the whole setup very unstable since the last firmware upgrades (ER7212PC v1.0 is on f/w 1.1.2 & SG2008P v3.2 is on f/w 3.20.1). The Force Provision error existed before the router was upgraded, but the DHCP issue is a lot worse since the router was upgrded (before, there was some issues with some dynamic addresses being issued to static clients (which is why I upgraded the router f/w), but all clients actually got an address, but now about 20% have none at all).

Do you make changes very quickly before the first change is successfully synced?

If you make a change to the device, it has not finished its sync and you make another change, this will cause a problem and error like this. This is expected to be normal.

Hi!

In my case the error log entry appears immediately after saving a configuration.
This is very irritating, as the ER7212PC combines the controller and the router in one device.
How long could it take to send/receive a simple configuration update command within an electronic device?
As the saved configuration is not coming into effect, unless I explicitly click 'Force provision', the issue seems to be due to faulty programming of the ER7212PC.

@TP-Link engineers:
What do you want to contribute to solving this issue?

Do you have the Application Result feature on your controller in your current firmware? Take a screenshot for me after you save a new change.

Or if possible, share a short video.

Make sure that nothing is changed, it has been synced to the latest config. And make a single change, will this show up?
