Hi Harsh Khandal,

seeing a 429 throttle message when u are just trying to build something new is a real mood-killer. but it is a common one, so let us get u unblocked.

this throttle is not about u doing something wrong. azure has built in limits on how many app service plan create operations u can do in a certain time window. it is a safety measure to prevent runaway scripts from creating a thousand plans by accident. your subscription just hit that limit.

for your microsoft azure solution, the fastest fix is often to just wait a little bit. these limits usually reset after a short period, like an hour or so. go grab a coffee, then try creating the web app again. it might just work.

if u are in a huge rush and cannot wait, u have another option. instead of creating a new app service plan, try using an existing one if u have one already in your subscription. when u are in the creation flow, look for the app service plan section and click 'create new'. but then, change the dropdown to 'select existing' and pick a plan that is already running. this avoids the create operation entirely and should bypass the throttle. our docs talk about plans here https://learn.microsoft.com/azure/app-service/overview-hosting-plans

also, check this. were u by any chance running a script or a pipeline that was trying to create and delete plans repeatedly? that is a surefire way to hit this limit. if so, u might need to add some delays or error handling into your code. this might help in other tools too that have similar rate limits.

if the issue persists for more than a few hours, then it is definitely time to contact azure support. they can look up your subscription and see the exact throttle limit and maybe even reset it for u. just go to the help + support section in the portal and open a ticket. give them that error message and your subscription id.

good luck. i know throttling errors feel like a wall, but it is usually just a temporary speed bump. your app will be up and running in no time.

Best regards,

Alex

Just had the similar issue with getting 429 while creating AppService Plan on free trial account. Message didn't say 'try again after xxx second's or so, but just 'Contact support', which is a bit difficult on free tier. Problem persisted even after I waited for 12+ hours. And no, single request in several hours should not be TOO MANY.
The actual resolution was to change to different location. Moved all resources from initial 'Central Us' to 'Canada' and error disappeared.
Obviously for Production environment you might need specific region, but ... in that case you probably will already have some real subscription with support from Microsoft ;)

Hi Harsh Khandal,
The error message you are encountering indicates that the App Service Plan Create operation is being throttled for your subscription. This typically happens when there are too many requests being made to the Azure service, exceeding the allowed limits for your subscription

If you are making multiple requests in a short period, consider spacing them out.

You may be hitting the limits for your subscription. Review the service limits for Azure services to ensure you are within the allowed quotas.
