Hi Kevin.
It is hard to say, as it can be caused by various reasons. Feel free to open the case and share its ID.
Failed to call RPC usually means its firewall blocking or permissions issue. Having that error code, my bet would be on permissions.
Thanks!

what kind of the permissions setting ? where I can set it ?
how if still able backup but have permission issue?

Check remote WMI calls on that machine using same account specified under agent connection settings.
Something like https://www.veeam.com/kb1926

Yup, same access denied error, however now on the repository level.
Try running some WMI call against that machine from VBR server using same credentials used in that repository settings(KB in a previous post), like "wmic path win32_computersystemproduct get uuid" or "select * from Win32_OperatingSystem".
