Access url not working

Hello.

What you are checking in the AWS Management Console is the IAM user information.
The information you are trying to enter in Visual Studio is IAM Identity Center information, so it will be different.
Please check the following document for the difference between IAM Identity Center and IAM users.
https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction_identity-management.html#intro-identity-users

If you want to create IAM Identity Center users, you need to set up IAM Identity Center.
https://docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/sso-credentials.html

For IAM users, you need to issue and configure an access key.
When you set up IAM Identity Center, you can see the "AWS access portal URL" as shown in the image below.

Thanks so much for your answer. I dont have Identity Center set up - I dont have an identity source like Active Directory and I am on the free plan - but Visual Studio seems to want an Identity Center identity and I cannot work out how to get it to accept my IAM user

How do I get it to accept my IAM user?
