AWS APP Studio Sign in failed

It appears you're having trouble signing in to AWS App Studio. The error message suggests there might be an issue with accessing your identity provider, which for App Studio is typically IAM Identity Center.

This could be due to several reasons:

1. You may be using incorrect credentials. When setting up App Studio without an existing IAM Identity Center instance, each user should have received an email invitation to join IAM Identity Center. You need to accept this invitation and create a password for your IAM Identity Center user credentials. Then you can use these credentials to log into App Studio.

2. If you've already set up credentials but can't remember your username or password, you'll need to contact your administrator. They can use the IAM Identity Center console to view your username or reset your password.

3. You might be trying to sign in using the wrong method. IAM Identity Center users need to use their specific access portal URL rather than standard IAM user sign-in pages. The access portal URL typically includes "awsapps.com/start" or "signin.aws/platform/login".

4. There could be a temporary system issue with App Studio or IAM Identity Center.

I recommend checking if you're using the correct credentials, contacting your administrator if you need help with your username or password, or trying again later if it's a temporary system issue. The error is not necessarily indicating that the service is "down" but rather that there's an authentication issue that needs to be resolved.
