Linux App Service with PHP - Error - "This region has quota of 0 instances for your subscription. Try selecting different region or SKU"

Brett Parkhurst 21

I'm struggling creating a Linux App Service for PHP in the US West 2 region. The Create resource walks me through everything perfectly and when I go to create it, I get the following error. We don't know why this is happening or how to check our quotas for a Linux app service in this region.

"properties": {

    "statusCode": "BadRequest",

    "serviceRequestId": null,

    "statusMessage": "{\"error\":{\"code\":\"InvalidTemplateDeployment\",\"message\":\"The template deployment 'Microsoft.Web-WebApp-Portal-68ee9e04-9d8f' is not valid according to the validation procedure.

Good to have a check on App Service Plans - List Usages. This will show the quota for the app service in this region.
Here is the link showing the usage

Hi Manu,

Thank you so much for the quick answer. I'm actually not sure what this API is telling me. What should I be looking for to figure out why I can't create a Linux App Service in the US West 2 region?

Very much appreciated!

I am also able to reproduce the similar issue as shown in the below screenshot

When you got to the details, you can see the link to go and check the usage+quota as below

This is basically go under your subscription settings. Select the region showed a quota limitation and see what is stopping us to create a resource there

In my case, it is the Network watchers. How it is for you?
There is an option to request Microsoft to increase the quota of the resource which is exceeding. Highlight the resource and go for a request, if it really need to increase. On this page, you will understand, if you need to adjust some other resource usage, so that the app service plan can be created successfully

As a final point, if you see that this is by an issue, create a support request by visiting the link shown at the Summary page of the app service creation

Manu, thank you so much! It is exactly our same resource that is exceeding quota. I wish the error would give you more information to exactly what exceeded the quota.

I am not sure what Network Watchers is, so I will read up on it, but I have requested an increase to help us create this Linux PHP server in West US 2.

Thank you so much!

While Microsoft is checking this, you may also see if there are any other workloads in the same region in your Azure subscription. If there is not, Microsoft has to help on fixing it.

Azure Network Watcher provides tools to monitor, diagnose, view metrics, and enable or disable logs for resources in an Azure virtual network

@BrettParkhurst-729 We are sorry to hear you are encountering this error.

We request that you open a free billing and subscription support ticket here if you have not already. This team will be able to review any quota increase requests or provide further context as to why the Network Watchers service quota has been hit.

As always, please share the outcome of the case here with the community in case anyone else has this issue.

Thank you, I have opened a ticket with Microsoft and they have confirmed that you can only have 1 Network Watcher per subscription and that is not the issue. I do not have an answer from them and am hopeful to do a live session tomorrow. I literally cannot find ANY information on why I can't create a Linux App Service in West US 2. I've tried every pricing tier available and it will not allow me.

@Manu Philip @Brett Parkhurst @brtrach-MSFT
I am also getting the same error as mentioned in the question and not able to create App Service Plan or Function App. But checked my Quota section and the only resource with very high usage is Network Watcher.

But it does not seem like this should be an issue as there can be only one Network Watcher per region per subscription, so this should be fine. Can anyone help here on what can be causing this issue and how to check from Portal as what resources are not there and not letting create the App Service Plan/Function App.

So it looks like Linux App Services are not supported right now in West US 2. Very unfortunate. Here is Microsoft's answer which is not great.

----------------------------------------------------------------------------

I really appreciate your time during the call. I'm sorry for this situation, but as I mentioned Microsoft has specific resources available in every region. Right now the location West US 2 seems to be highly demanded and there are no available instances to run your App Service, that's why you are able to create the App in other regions but not this specific one. To migrate apps or clone them it's also necessary to create an App Service in the process as you can check here: Move an app to another region - Azure App Service | Microsoft Learn, Create, Clone, Browse, Restart, Stop And Delete Web App In Azure (c-sharpcorner.com), so this issue keeps preventing us from having an app in this location. I suggest you try another region instead of waiting until there are available instances in West US 2 since we don't really know when could it be.

I will engage someone else in my scalation path so they can give you their point of view with this situation and maybe clarify the remaining doubts you may have.

It is unfortunate to know that the interested region is not suitable for the deployment. If it doesn't stop anything, how about creating the app in a different region and move to the US WEST 2 sometimes later when it supports. Here is the document shows moving the app between regions: https://learn.microsoft.com/en-us/azure/app-service/manage-move-across-regions

Yea that is what we are going to do, but it will require some more advanced VNet connection from Central US to West US 2 to be able to connect it in with our on premise resources. We already have a V-Net setup in West US 2 back to our internal systems. Unfortunately, I had to host this up on a box inside our network to get my urgent need dealt with.

Thanks Manu for all the support, you rock! Have a great day!

When you get time, could you please mark the answer as it finds the reason for the error message you are facing and see how/what resources has exceeded the quota? This will help others who are facing the similar kind of situations. Have a great time with Azure and a great day !

This is in poor taste since PlayFab's new cloud scripts require us to use Azure functions and PF is located in this very server (USW2). This means we have to pay 50% more or clients will face latency.

@DylanHunt-3642 I am not sure I understand the issue you are facing.

The resource limitation in US West 2 has been resolved back in February and Linux App Service Plans are now able to be created in USW2. We run resource reallocation tasks a few times each day to ensure these situations are resolved in a timely manner.

I confirmed this by creating a S1 tier Linux Web App in USW2.

If you are encountering a specific error, please share it here with us. Otherwise, any resource availability issues should be resolved.

@brtrach-MSFT - I have been trying to create a Linux app service plan on USW2 since yesterday - and again today. No dice. USW1 is the same. Earlier, I had it work for Windows (now deleted), but not Linux.

As a quick update -- I just now created one in US West 1 (that had the same error yesterday; not today), but not US West 2. While it's quite close to USW1, latency is incredibly important for gaming; I need to be on USW2 where PlayFab resides. How to go about this?

EDIT: I had a bad name, so I went to make another one in USW1 -- nope, that's it again. I can't make another (same error). Maybe it's a race vs other customers? Either way, for enterprise services, I'm a bit shocked that the error message was so useless. I checked out my quotas for a sanity check and all down the line is 0% use. If aware of this issue, how come Microsoft doesn't give it a proper error so users don't go crazy figuring out what's wrong?

EDIT 2: Cannot do free tier in USW3 in Linux, even for testing purpose for PlayFab:
