Error #0158: connection attempt under standard account for the domain user
When connecting to the server during a login session, you are trying to enter with a regular or passwordless authorization type, but the account of this user is a domain one.
Check the user's account type that you are trying to authorize. Admin Panel, the section "User list".
There are 4 types of MyChat accounts:
1.Regular — login and password. You can use UIN, nickname or email as a login.
2.Domain — login and password. A domain name is used as a login (domain/login).
3.Passwordless — only login is used. You can use UIN, nickname or email as a login.
4.Transparent domain — is used automatically, you can't choose this authorization type manually.
Check the authorization type that is set for the user account. It must be (1) or (2).
