and in solidcp event log i have this error that is related to authentication issue:

[11/17/2021 2:31:48 PM] ERROR: 'hMailServer 5.x' CreateDomain
System.Exception: Could not authenticate using administrator credentials provided
   at SolidCP.Providers.Mail.hMailServer5.get_hMailServer()
   at SolidCP.Providers.Mail.hMailServer5.CreateDomain(MailDomain domain)
   at SolidCP.Server.MailServer.CreateDomain(MailDomain domain)

i configure email server as below:

1 - select hmailserver 5.x as a provider

2 - in Service Settings

     - puplic ip address is my server IP address that hmailserver has been installed

    - admin login is my hmailserver admin username

    - admin password is my hmailserver administrator password.

also, if Create "Catch All" Mail Account remain unchecked hosting space created correctly but none of NS records defined in mail service applied to domain for witch i create hosting space and after that it is impossible to create email account also.

nOTE : I use windows server 2019

how i can solve this problem
