The subscription is not allowed to create or update the serverfarm

yes, but no solution. They simply says its technical issue and only azure support team can address. Further, We are reaching out to inquire whether any recent restrictions have been imposed on the utilization of Azure passcodes. We have encountered significant difficulties accessing the Azure student passcodes, particularly during AZ 400 training sessions over the past few months.

During these training sessions, participants consistently encounter the following error:
{
"status": "Failed",
"error": {
"code": "Forbidden",
"message": "The subscription 'aacb3810-b205-4b2c-8405-09a8ba2848f2' is not allowed to create or update the serverfarm.",
"details": [
{
"message": "The subscription 'aacb3810-b205-4b2c-8405-09a8ba2848f2' is not allowed to create or update the serverfarm."
},
{
"code": "Forbidden"
},
{}
]
}
}

Additionally, we have observed that the Free tier is displaying as 0, despite deleting all VMs and services. We are unable to create any new services, including those under the Free tier, either via the Bicep template or directly through the portal. This issue persists across multiple regions.

This error has become a recurring obstacle during our training sessions, and it is increasingly challenging to reassure our students. It appears that Microsoft is consistently blocking these actions, and we urgently require resolution and clarification on this matter.

We appreciate your immediate attention to this issue and request a prompt response.
