In certain scenarios, a database that has inconsistent data may cause this error. In most cases, database reset will be required to restore the data and structure without losing vital configuration or prior recordings.

For specific instructions, please review the article appropriate to your NVR operating system:

ATTENTION:A backup of the NVR's configuration will be needed to retain all settings. In general, a best practice is to create a backup whenever any additional cameras have been added, a password has been changed, or there has been any other configuration change on the NVR. If at this moment a recent backup is not available, and the UniFi Video UI is inaccessible, find suitable backup files in:
  •  /usr/lib/unifi-video/data/backups/ (UVC-NVR and Linux)
  • C:\ProgramData\unifi-video\data\backups (Windows)

SSH or an FTP client will be needed to obtain a backup from a UVC-NVR or Linux system.
