Increase custom domains limit from 500

Question

Hello,

We are getting a "Too many(501) custom domains. Limit is 500" message on our Azure function. Is there a way to increase that limit?

Answer 1

Hi @Matt Ferguson ,

you could try to contact Azure support to increase the limit:

• Navigate to your subscription in the Azure Portal
• Click on Usage + Quota
• Click on Request increase
• Select Other Request in the Quota Type field
• Fill all other fields of the request

Maybe this will work for your requirement

Hi @Matt Ferguson

Welcome to Microsoft Q&A! Thanks for posting the question.

Unfortunately, the max number of custom hostnames allowed for a single app on App Service is 500 and it cannot be increased.
