Troubleshooting Amazon GameLift identity and access

Use the following information to help you diagnose and fix common issues that you might encounter when working with Amazon GameLift and AWS Identity and Access Management (IAM).

I am not authorized to perform an action in Amazon GameLift

If the AWS Management Console tells you that you're not authorized to perform an action, contact your AWS account administrator for assistance. Your administrator is the person that provided you with your sign-in credentials.

The following example error occurs when the mateojackson IAM user tries to use the console to view details about a queue but doesn't have gamelift:DescribeGameSessionQueues permissions:

User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: gamelift:DescribeGameSessionQueues on resource: examplequeue123

In this case, Mateo asks his administrator to update his policies to allow him read access for the examplequeue123 resource using the gamelift:DescribeGameSessionQueues action.

I am not authorized to perform iam:PassRole

If you receive an error that you're not authorized to perform the iam:PassRole action, your policies must be updated to allow you to pass a role to Amazon GameLift.

Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.

The following example error occurs when an IAM user named marymajor tries to use the console to perform an action in Amazon GameLift. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the role to the service.

User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole

In this case, Mary's policies must be updated to allow her to perform the iam:PassRole action.

If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.

I want to allow people outside of my AWS account to access my Amazon GameLift resources

You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.
