Hi there. We've been with TalkTalk for a couple of years now and up until now, we've had no problems whatsoever.
Around 1:30 AM yesterday, I got a notification on my phone that our Nest Indoor camera lost its connection. In the morning, I could see that several other Nest devices including thermostats and smoke detectors were showing on my phone as offline. This initially led me to suspect it was a Google problem. However, our external security camera (a non-Google device) is also not accessible via my phone.
We use a TP-Link Deco system for our wifi, and so have wifi switched off on the TalkTalk router itself. I don't think it's a problem with the wifi, as within the Deco app I can see all the afflicted devices showing up as connected to the wifi and transferring data. Indeed, I can actually reach out to the Internet on the devices that have an interface to do so, e.g. I can check for a software update on the thermostats and it comes back saying no update is available - all looks normal.
The one thing all the affected devices have in common is they require external access in order to work, i.e. the ability to connect from outside the home. This is leading me to suspect it's a TalkTalk issue.
I've tried all the usual, disconnecting and reconnecting everything (left the router unlpugged all night) and have tried a factory reset on the Nest camera, but to no avail.
I'm at a bit of a loss as to how to proceed! Any help would be massively appreciated.
