Certbot: Intentando que Certbot instale un nuevo certificado con HSTS

Hola,

Algunos antecedentes:
Entonces, estoy usando InterWorx y me encuentro con este problema en el que ./certbot-auto --hsts no funciona ni ./certbot-auto certonly --standalone después de detener temporalmente httpd en CentOS 7 x64 . También tenga en cuenta que no es un proxy. Esto es en un VPS Xen. También he confirmado que telnet al puerto 443 funciona para este servidor, por lo que no debería haber problemas de conexión ...

IW dev / support señaló que HSTS podría estar causando que Certbot-auto falle en helmsgate.eidolonhost.com porque eidolonhost.com está precargado a través de la lista de precarga de HSTS (que ahora solicité la eliminación para poder solucionar este problema ... .) pero esperaba que hubiera alguna respuesta en la que pueda forzar la instalación de un certificado LE.

Editar: tenga en cuenta que helmsgate.eidolonhost.com ahora está usando un certificado SSL válido de Comodo. Al menos me permitirá reemplazar el certificado SSL con Let's Encrypt en el futuro.

Edit2: parece que todavía persiste para un dominio de cliente, en este caso, dragonfox.net con exactamente el mismo error. El cliente está usando CloudFlare en este caso, sin embargo, no sé si eso es relevante para que el cliente no pueda instalar nuevos certificados SSL.
