  2. Open the registry and navigate to the HKEY_LOCAL_MACHINE\Software\Veeam\Veeam ONE Monitor\Service registry key.

  3. Create a new entry with the following parameters or modify if exists:

    Name: MaxTimeDiff

    Value: the value that can cover the time difference in seconds

  4. Start Veeam ONE Monitor and Veeam ONE Reporter services.
