password reset not working on debian 11

i created a ssh local user provider for a debian 11 box with root user credentials
test connection works
scan configuration runs without error but doesn't return any users
i the log i see the following error:
SshExpectException - Time out when trying to find '[sudo] password for root: '

at Devolutions.Server.Pam.SshCommand.SshExpectation.Execute(PamCredentialBO bo, SshTerminal shell)

i manually created a pam user which exists on the debian box and "check synchronization status" is successful
but if i click on "reset password" the following error occurs:

SshExpectException - Time out when trying to find 'password:'
