Hello,
I’m having the exact same issue. I have installed the plugin on 7 websites and it works perfectly except for 2 of them (same shared hosting plan).
– I’m logged in as admin
– The cname records exist for a long time
– I’m using the plugin version 5.7.1 with WordPress 5.8.1
I receive the message “Authentication failure! Please try again” when I check the checkbox : Generate SSL Certificate for both www & non-www version of domain.
If I uncheck this checkbox, I receive the message “Could not verify DNS records. Please check whether you have added above DNS records perfectly or try again after 5 minutes if you added DNS records just now. Upgrade to PRO version for fully automatic domain verification”.
Here is the debug log :
5.7.1 SINGLE DOMAIN SSL 1 - https://site.com
Domain covered:
["site.com"]

The http challenge reports this error : “Could not verify HTTP challenges. Please check whether HTTP challenge files uploaded to acme-challenge folder is publicly accessible. Some hosts purposefully block BOT access to acme-challenge folder, please try DNS based verification. Upgrade to PRO version for fully automatic domain verification.”
Any help would be greatly appreciated.
Thank you very much for sharing this plugin.
