Certbot failing to verify on IIS

I’ve created the .well-known\acme-challenge directories, checked their permissions, and can access a test file I placed inside:

My domain is: test-engine.eleutian.com

I ran this command: certbot certonly --webroot

It produced this output:

Domain: test-engine.eleutian.com
Type: unauthorized
Detail: Invalid response from
[2600:9000:21eb:6800:19:266c:200:93a1]: " \n<html

My web server is: IIS 10.0.14393.0

The operating system my web server runs on is: Windows Server 2016

My hosting provider is: AWS

I can login to a root shell on my machine: Yes

I’m using a control panel to manage my site: no

The version of my client is: 1.5.0


Hi @msmith1372

you have an IIS. So files with file extensions aren’t a real test.

Change the file name to test without an extension.

And you have a redirect http -> https. Has your http the same webroot as your https?

PS: You have ipv4 and ipv6. But it looks like these are the same servers - no different answers - see https://check-your-website.server-daten.de/?q=test-engine.eleutian.com
