There are following possibilities:
- Check the network connections from NVR to your router.
- Check the device P2P function is enabled or not. (Main menu*>Setting*>Network*>P2P)
- Check cell phone P2P login information is correct. You will need to ensure the user name and password are correct. (This is the credentials for logging into the system.)
- Check P2P SN is right or not. You can use the cell phone to scan the QR code on the device P2P interface (Main menu*>Setting*>Network*>P2P), or you can use the version information of the WEB to confirm. (For some previous series products, the device SN is the main board SN, it may result in error.)
