I am attempting to create an a Quick Suite instance with an account level IAM Identity Center instance in the AWS console in us-east-1. I have currently setup an account level instance that is using Okta. I do have an organizational instance, but that is intended for logging into the console and must remain separate. I have been following this [guide]( Manage access to insights with an account instance of AWS IAM Identity Center and Amazon Quick Sight ) however in the signup page, the IAM Identity Center instance we created within the account does not appear.
See the following image:
I inspected the network tab in browser and there were several API calls with 403 errors to IAM Identity Center in other regions other than us-east-1 where my current IAM IDC is located. Unsure if this is related, but here are the responses:
{
“Message”: “User: arn:aws:sts::XXXXXX:assumed-role/MY_ADMIN_ROLE is not authorized to perform: quicksight:subscribe on resource: arn:aws:quicksight:us-east-2:XXXXXXXX:* with an explicit deny in a service control policy”
}
