Applies to: All Reolink cameras and NVRs with the UID

Reolink UID (based on P2P) can be used for the set-up and remote access of Reolink cameras and NVRs. If you get Login failed/Connection failed/Timeout error message when trying to remotely access the camera via the UID, please follow this guide for a simple troubleshooting.

Note: Please make sure you can log into the your deivce on the LAN before the troubleshooting.

There are several possible causes for the problem:

Cause 1. Incorrect UID and settings.

Solution: Check your UID to see whether the UID you enter is correct; enable UID for your device, and try to log in again. 

Cause 2. The UDP ports are blocked by the network firewalls.

Solution: Please log in your router to confirm whether the UDP ports have been enabled or not. If you couldn't find this setting, please contact the router support for some help. 

Cause 3. Your device is blocked by the system firewall of the login terminal.

Solution: See how to configure system firewall settings and allow Reolink Client to pass through the system firewall on windows 10 or on Mac

Please also reboot the device, and change another router/network if possible. 

Note: If you fail to log into your device via UID on Reolink App, please switch to another network (switch to 4G or another Wi-Fi) and try it again.

If the problem still exists after going through the steps above, please check your system status via Reolink App, take a screenshot, and send it to our support along with your device UID for help.
