- Plesk for Windows
Let's Encrypt certificate for a particular domain in Plesk for Windows can not be renewed automatically with the error message below:
Failed to renew certificate of domain 'example.com': Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/13769068820.
Detail: Fetching https://acme-challenge.localhost:443/.well-known/acme-challenge/jhpl_titvpnxqcffch5s9semwhzx1ytmjnhnngeyqek:
Invalid hostname in redirect target, must end in IANA registered TLD
In the document root of the affected domain, there is the file
In IIS > Servername > ISAPI Filters
ISAPI_Rewrite_x64 filters points to :
In IIS on the affected domain, the third party ISAPI filter "ISAPI_Rewrite 3" (Apache .htaccess mod_rewrite compatible module for IIS) is enabled.
- Go to Domains > example.com > File Manager page and rename the file
I have this issue but I don't have a .htaccess file or the ISAPI_Rewrite 3 filter. I believe it has to do with HSTS "Redirect Http to Https" being enabled.
When I disable this setting, the renewal is successful.
