Why Does IAM User Login Fail?

Symptom

An IAM user fails to log in and sees a message indicating that the username or password is incorrect or login from the current device is not allowed by the access control rules set by the administrator.

Troubleshooting

• Incorrect username or password
  1. Possible cause: The domain name or IAM username is incorrect.

     Solution: Enter the correct domain name and IAM username. If you do not know the IAM username or the domain name, contact the administrator.

  2. Possible cause: The password is incorrect.

     Solution: Enter the correct password (pay attention to letter cases).

  3. Possible cause: You did not clear the browser cache after changing or resetting the password.

     Solution: Clear the browser cache and log in again.

• Login from the current device is not allowed by the access control rules set by the administrator.

  Possible cause: The administrator has set access control rules on the IAM console to limit access from specific IP address ranges, IPv4 CIDR blocks, or VPC endpoints.

  Solution: Contact the administrator to check the ACL rules on the console and log in to the cloud service platform from an allowed device, or ask the administrator to modify the ACL rules.
