Web App creation fails with "Operation cannot be completed without additional quota" — Current Limit (Total VMs): 0 in every region, quota increase also denied

I'm trying to create a Web App (App Service) and every attempt fails at Review + Create with this error:

Operation cannot be completed without additional quota.

Current Limit (Total VMs): 0

Current Usage: 0

Amount required for this deployment (Total VMs): 1

(Minimum) New Limit that you should request to enable this deployment: 1

What I've already tried:

  1. Different SKUs — started on Premium V4 (P0V4), switched to Premium V3 (P0V3). Same error both times.
  2. Different regions — tried East US and West US. Same error, so it doesn't look region-specific (the estimated price changed between regions, confirming the region actually switched).
  3. Requested a quota increase for P0v4 VMs in East US. This failed with a notification: "We were unable to adjust your quota. Submit a support ticket so that a support engineer can assist you in adjusting your quota."

My Quotas page shows the Pv4 family at "0 of 30" for the region, but the deployment error says the **Total VMs (regional cores)**limit is 0.

Questions:

  • Is "Current Limit (Total VMs): 0" a subscription-level restriction rather than a regional one? It behaves the same in every region I try.
  • Does this mean my subscription type (I need to confirm which one — possibly a free/student/trial subscription) is blocked from creating VM-backed App Service tiers entirely?
  • Is switching to the Free F1 tier the correct way to avoid consuming VM core quota, or is a Pay-As-You-Go upgrade / support ticket the only real path if I want a dedicated (Premium) plan?

Any guidance appreciated.

Those are two different quota dimensions. The “0 of 30” Pv4 value is the per-family allowance, while the deployment is being blocked by the regional Total VMs limit. A family allowance cannot be used when the total limit is zero, so changing from P0V4 to P0V3 will not help.

Seeing the same result in multiple regions strongly suggests an offer/subscription eligibility restriction, although each region still has its own quota. Check the subscription’s offer type under Subscriptions > Overview. Microsoft states that Azure Free Account and Azure for Students subscriptions are not eligible for quota increases. If that is your offer, upgrading to Pay-As-You-Go is the practical route for a dedicated App Service plan.

If this is already a paid subscription, open Help + support > Create a support request, choose Service and subscription limits (quotas), then App Service. Include the subscription ID, target region, exact SKU, requested instance count, and the failed quota-request details. Quota/subscription support does not require a paid technical support plan.

F1 uses shared compute, so it does not request a dedicated Premium worker and may work for development/testing. It is not an equivalent workaround for Premium: it has CPU/feature limits, cannot scale out, and has no production SLA.

Hi @Mohan TechOps

Thanks for reviewing our recommendation. Could you try switching the region for now and see whether you’re able to create the web apps? We’re also working on this in the meantime. Please let us know whether webapp creation works for other locations/regions.

    Hi @Mohan TechOps

    There are still some bugs/quirks in the new App Service self-service quota.

    Now that you have upgraded your subscription to Pay-As-You-Go, try increasing one of the East US App Service SKU quotas by 1. Doesn't really matter which SKU.

    For example, please go to the same App Service quota screen you have in your screenshot, click on the pencil icon next to B1 VMs, and request increase by 1 (so if it is 30 now, request 31 for new limit). If your request is approved, you should see Total Regional VMs automatically increase to 0 of 31, and then your deployment of P0V3 or P0V4 should succeed, assuming there is available capacity.

    Please reply back with your results, whether positive or negative.

    Thanks.

    Hi @Mohan TechOps

    Greetings for the day, Thanks for reaching out to Q&A.

    After reviewing your post, we tried to create Web App and received the same error on our first attempt. Please see the error screenshot below.

    After some time, we deleted all the unwanted/draft Web Apps in our environment and tried creating the 4 Web Apps , and everything worked without any errors. Please refer to the attached screenshot below. This appears to be intermittent on the platform, so could you please try clearing the browser cache, signing out of and back into the azure account, and trying again to create a web app.
