Sending an ACME HTTP validation request to epyc.org results in an unacceptable redirect. This is most likely a misconfiguration of your web server or your web application.
It appears that a redirect was generated by your web server that is missing a trailing slash after your domain name: https://epyc.org.well-known/acme-challenge/letsdebug-test. Check your web server configuration and .htaccess for Redirect/RedirectMatch/RewriteRule.
