The subscription is not allowed to create or update the serverfarm

Question

I've followed this post(https://learn.microsoft.com/en-us/answers/questions/1657059/the-subscription-is-not-allowed-to-create-or-updat), including waiting and switching regions. but now I still can't deploy it successfully, is there any other way to use it?

And since I'm a student subscriber, I can't submit a work order to change this issue.

        "message": "The subscription '9be0bb48-3b16-420b-a08a-511ae29741f6' is not allowed to create or update the serverfarm.",
        "details": [
            {

            },
            {
                "code": "Forbidden"
            },
            {}
        ]
    }
}
