VMware Cloud Director, vApp backup error

Hello
We set up integration according to the documentation: Avamar server + Data Domain + VMware Cloud Director Cloud Director Data Protection Extension + VMware Cloud Director

Everything went up without errors.

Everything breaks when I run a backup. Backup fails with error:

I can't understand why: login failed - logins disabled or invalid user-id or password

All policy settings and task execution are made under one user MCUser, and he is the system administrator
