Hello, I configured Hestia on my server (let’s say mail. domain. com is the main domain). After I added a regular user and added the mail root domain (domain. com) using that user.
Now I’m trying to enable SSL (Let’s Encrypt) for webmail but it doesn’t work because Hestia already assigned a certificate to mail. domain. com. There’s a message saying that it will create for both webmail and mail subdomains:
webmail .domain .com To enable Let’s Encrypt SSL, ensure that DNS records exist for mail. domain. com and webmail. domain. com!
This is the error message:
Error: Let’s Encrypt validation status 400 (mail. domain. com). Details: 403:"The key authorization file from the server did not match this challenge
How can I fix that?
