Error Code RequestDisallowedByAzureMessage: Resource was disallowed by Azure: This policy maintains a set of best available regions...

Question

I'm using the student subscription and I receive this error whenever I try to create a Static Web App that will be used to host a React frontend. I am aware of the regions available through my student subscription which are:

["northcentralus","canadacentral","westus","southcentralus","westus3"]

I've tried all regions and still receive this same error for all of them. Is there anyway that I'll be able to create a Static Web App?

Hi @Sean Tisdale

Thanks for Reaching us regarding your issue

The error you’re seeing (RequestDisallowedByAzure) is expected with an Azure for Students subscription when creating an Azure Static Web App. Student subscriptions are restricted by Azure Policy to a small, subscription‑specific set of regions. At the same time, Static Web Apps are supported only in a limited number of backend regions.

In your case, those Static Web App regions don’t overlap with the regions allowed for your student subscription, so the deployment is blocked regardless of which region you select. This is a subscription limitation and can’t be overridden.

What you can do next:

• Use Azure App Service to host your React app instead. App Service supports many more regions and works reliably with Azure for Students.
• Upgrade to a Pay‑As‑You‑Go or standard Azure subscription, which removes the region policy restriction and allows Static Web Apps to be created normally.

You can also review your allowed regions under Azure Policy >Authoring >Assignments > “Allowed resource deployment regions”,
https://portal.azure.com/#view/Microsoft_Azure_Policy/PolicyMenuBlade/~/Assignments
but please note that even if a region appears there, Static Web Apps may still be blocked due to backend service placement.

Hi Sean,

Unfortunately Azure Static Web App (SWA) can only be deployed to five different regions, and none of those regions are in the allowed list for your Azure for Students subscription. You may consider using Azure App Service instead, or you could upgrade to Pay-As-You-Go subscription.

Answer 3

The error indicates that a region access/optimization policy is applied to the subscription, and that policy is blocking Static Web App creation in all regions being tried, even though they are normally allowed for the student offer.

This is not a quota or template issue; it is an Azure region-access policy issue. The policy text in the error matches the region optimization / region access policies described in the documentation.

To proceed, there are only two supported options:

1. Try an alternative region that the policy allows for this subscription (if any are offered in the portal for Static Web Apps). If the portal shows a banner like “You can create resources in the following regions only…”, use one of those regions.
2. If no available region works for Static Web Apps, submit a support request to ask for region access for this resource type:
   • Sign in to the Azure portal.
   • Open Help + support and create a new support request.
   • In the problem description, mention the RequestDisallowedByAzure error and that the region optimization / region access policy is preventing creation of a Static Web App in any of the regions available to the student subscription.
   • Request that the subscription be granted access to at least one region that supports Azure Static Web Apps.

If support does not grant additional region access, Static Web Apps cannot be created in this subscription while that policy is in effect; another subscription without the restrictive region policy would be required.
