  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Resolved Let's encrypt Certs doe not get renewed and cannot be issued

Hi to all,
since several days I'm digging around a Certificate problem. We are using a Windows 2019 Server with Plesk Obsedian V18.0.29_build20200807.15

The renewal of the Let's encrypt certs worked like a charm, since no certificate was renewed about 15 days ago.
Whenever a certificate should be renewed (or created) I got the following message (for all of our daomins):
Could not issue an SSL/TLS certificate for <domain>
The authorization token is not available at http://<domain>/.well-known/acme-challenge/2-rwwaODhSgh6Kqli0110SpRdczjupnN0V6PsqSxGzU.
In the PHP error log:
[2020-08-12 10:29:35] ERR [extension/letsencrypt] Domain validation failed: Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/6478172285.

The token file is generated correctly in both folders:
c:\inetpub\vhosts\<domain>\httpdocs\.well-known\acme-challenge\
c:\Program Files (x86)\Plesk\var\acme-challenge\

When I try to access the token file (or another file in the acme challange directories with https://<domain>/.well-known/acme-challenge/2-rwwaODhSgh6Kqli0110SpRdczjupnN0V6PsqSxGzU. I get the expected result.

But when I try it with http (http://<domain>/.well-known/acme-challenge/2-rwwaODhSgh6Kqli0110SpRdczjupnN0V6PsqSxGzU. )
I get a 403 - Forbidden message
or
502 - Web server received an invalid response while acting as a gateway or proxy server.
(Depends on the <Domain>)
The credentials are set to anonymouse Access in Plesk and also in the IIS Manager.

I already tried to delete the acme folder, to repair the credentials, disabled/enabled http to https redirection.

Does anybody have an idea?

Regards

Thomas
 
I have the same problem - can't renew a cert - it did use to work seamlessly but no matter what I do I can't reissue a cert due to the same problem you mention above - 403 on the HTTP version of the file but can be viewed via https - I've followed the troubleshooting steps but am at a loss now as to how to fix. How did you resolve in the end?
 
I managed to fix this in the end. Loading up IIS and looking at the directory I just unticked the option to have SSL required. Now certs renew as expected without any problem.
