Azure LetsEncrypt extension cannot access .well-known / acme-challenge in Umbraco app

I host the Ubraco CMS app in Azure. Following the instructions in this blog post , I get the following error when trying to request and install a LetsEncrypt certificate using Azure Let'sEncrypt Site Extension :

System.Exception: The Lets Encrypt ACME server was probably unable to reach http://domain.com/.well-known/acme-challenge/token

I confirmed that all the settings of my application are correct, my extension was installed correctly and that there seems to be no network problems. What could be causing this problem?
