Allows you to encrypt an ACME Challenge file that is not accessible from IIS

Question

I am trying to create an SSL certificate for one of our projects that runs on Azure VM, which has no IP restrictions. However, the task file that is generated causes a 404 error and is not accessible via the Internet.

I tried the following:

• Moving static content type over extension options less in IIS
• Adding mime type for text / json, text / html

None of the above works, which makes it very difficult for me to create SSL using this service. Any idea how I can make it available? I gave full access to this particular application pool identifier, so permissions in this case do not seem to be a problem, namely how the smaller files are handled in IIS

Any help is appreciated.

Thanks, Vishal

Answer 1

You just add a new MIME type to IIS like this.

and try using url in your browser. you will see that now you can pass let-encrypt authentication :)

Answer 2

Inspired by the accepted answer, I did the following:

I used Plesk for Windows on Godaddy. Go to

Web server settings

In MIME types, add the following node and click OK.

text / plain

Note the dot at the end of the above parameter.

Answer 3

web.config, ACME 404

<remove fileExtension="." />
<mimeMap fileExtension="." mimeType="text/plain" />
<remove fileExtension=".*" />
<mimeMap fileExtension=".*" mimeType="text/plain" />
