What you'll notice
The app worked for months, then "device offline" — though the system records fine locally.
Why it happens
The ISP changed your public IP or moved you behind CG-NAT, a router replacement lost the port forwards, or the P2P service needs re-binding.
How we fix it
We re-establish the correct access path for your connection type — P2P re-bind or DDNS repair — and document the setup so the next router swap does not break it again.
Still not working?
If the checks above haven't restored your router & network, this usually needs a technician. Our Remote Viewing Setup service covers exactly this fault.
