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?

    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.
