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/Send UID failed message when trying to remotely access the camera via the UID, please follow this guide for a simple troubleshooting.
There are several possible causes for the problem:
Cause 1. The UDP ports are blocked by the network firewalls.
Solution: Refer to use NTP to synchronize time to check whether you can sync the time succeeded. If you can, it means that that UDP ports are opened. If not, please check the NTP settings and your local network settings to ensure that UDP ports are not blocked by the firewalls.
Cause 2. 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.
Cause 3. Unsuccessful email settings.
Solution: refer to Reolink Camera Email Test Failed and Sent Email Fail to check whether your email has been successfully set.
