CheckHttpChallenge failed

First, thank you for this awesome work. I added a certificate to one of my web app and it worked good, now I’m trying to add another certificate to another web app and I’m getting this error:

If you update Web.config under .well-known to the following contents, you should be able to avoid the above error.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <clear />
      <add name="StaticFile" path="*" verb="*" modules="StaticFileModule" resourceType="Either" requireAccess="Read" />
    </handlers>
    <staticContent>
      <remove fileExtension="." />
      <mimeMap fileExtension="." mimeType="text/plain" />
    </staticContent>
    <rewrite>
      <rules>
        <clear />
      </rules>
    </rewrite>
  </system.webServer>

Hi @brainmeyers

I found a way to get HTTPS without upgrading the AppServicePlan on Azure. The solution is to use CloudFlare. They have a free plan with a free SSL certificate. Check out this article: https://www.troyhunt.com/how-to-get-your-ssl-for-free-on-shared/

Thank you @flixius
