Basic user logins

Question

I am unable to log in using Basic User accounts in my Appian Cloud environment, while admin accounts are working fine. 
 I have verified that the users are active and have the required group memberships. Password reset was also attempted, but the issue persists. 
 Has anyone faced a similar issue or can suggest what configurations or logs I should check? 
 Thanks.

Could you clarify :
Are the basic users SSO users or native Appian authentication users?
What exactly happens when they try to log in; which screen do they land on (login page, blank/white screen, error page)?
What is the exact error message or behavior observed ( Invalid credentials, redirect loop, blank screen, session timeout)?

Basic to check ->
Verify the basic users are added to the Application Users system group and are logging in via the main Appian URL (not /suite/design).
Then check login-audit.csv to identify if the failure is authentication or authorization.

403 Forbidden means the users are reaching Appian, but Appian is rejecting access after sign-in, Check if site is under maintenance or Check if basic user is part of any of the application group or site/home page security. Check default landing page of user in admin console.

Try checkign the logs login-audit.csv and authz-audit.csv to find more details for the basic user. Also check the network capture when basic user tries to login (Inspect->Network->Request/Response) if it can give more info on the error.
