Unable to issue an SSL certificate using Let's Encrypt in Domains > example.com > SSL/TLS Certificates:
Could not issue an SSL/TLS certificate for example.com
Could not issue a Let's Encrypt SSL/TLS certificate for example.com.
The authorization token is not available at http://example.com/.well-known/acme-challenge/6AkQ-N5vdWobP0yM2Wq9jJ8S6TKt0R1DCXfsGUGCdAY.
To resolve the issue, make sure that the token file can be downloaded via the above URL.
The authorization token URL mentioned in the error can not be accessed via web browser failing with a 503 error.
The application pool
acme-challengestops when the authorization token URL is accessed via a web browser .
This can be checked in Windows, Internet Information Services (IIS) Manager > ServerName > Application Pools:
acme-challenge is not set/or doesn't have the correct permissions set to the app pool folder
Set the user
acme-challenge and/or delegate "Full Control" permission to the acme-challenge app pool folder.
Connect to the server via RDP
Right-click on the folder
C:\Inetpub\temp\appools\acme-challenge, then click on Properties.
On the Security tab, check that the
acme-challengeuser exists and that it has
full controlpermission on the folder.
Click Apply button.
Re-issue SSL certificate in Domains > example.com > SSL/TLS Certificates.
In my case the application pool
acme-challengestops when the authorization token URL is accessed via a web browser because "Enable 32-Bit Applications" was set to "True".
Set it to "False" resolved my issue.
Hi Wael Alsail, the issue you are describing seems slightly different. I will test it and create the necessary documentation.
There is no acme-challenge user to add full control. Any idea what to do next?
