Azure LetsEncrypt 403

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: AzureLetsEncrypt extension

It produced this output:

Unable to complete challenge with Lets Encrypt servers error was: {“type”:“http-01”,“url”:“",“status”:“Invalid”,“validated”:null,“error”:{“Type”:“urn:ietf:params:acme:error:connection”,“Detail”:"Fetching Timeout during connect (likely firewall problem)”,“Identifier”:null,“Subproblems”:null,“Status”:400},“errors”:null,“token”:“sgwPAICFJYvNyHxTdd4vBbJVSbyOL8SBByFyizUTZmg”,“keyAuthorization”:null}

Strangely going direct to in a browser succeeds ok.

My web server is (include version): azure web app service

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: Azure

I can login to a root shell on my machine (yes or no, or I don’t know): No

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

Help would be very much appreciated

Hi @Alanw

your configuration can't work.

Your ip addresses -

Host T IP-Address is auth. ∑ Queries ∑ Timeout A Dublin/Leinster/Ireland (IE) - Microsoft Corporation No Hostname found yes 1 0
A Scottsdale/Arizona/United States (US) -, LLC Hostname: yes 1 0
AAAA yes A Scottsdale/Arizona/United States (US) -, LLC Hostname: yes 1 0
AAAA yes

But checking an unknown file in /.well-known/acme-challenge

there is the wrong answer - a frame. So the validation file is invisible.

<html> <head> <title>Milsitios</title> <meta name="description" content=""> 
<meta name="keywords" content=""> </head> 
<frameset rows="100%,*" border="0"> 
<frame src="" frameborder="0" />
 </frameset> </html> 

Is this

your domain? If yes, you have to change your DNS, so you use a CNAME.

Or use the ip of that domain directly.

Yep - has the ip address. So remove the GoDaddy ip of your non-www and change the ip address of your www.
