Encriptar con múltiples dominios no funcionaba para certificados ECC

También tendrías que revisar el ecc, pero creo que todo encaja.

Sí, así es como todo debería funcionar.

OK. Estamos listos. Gracias de nuevo por tu persistencia. He marcado tu publicación que señala el problema como la solución.

Ya pregunté en otra publicación si tiene sentido mantener el certificado rsa obsoleto, espero que se elimine pronto.

Algo no está del todo bien. Acabo de eliminar los certificados antiguos y he creado nuevos con la siguiente reescritura, pero el certificado tampoco se ha creado para www:

cat /var/discourse/containers/app.yml
  after_ssl:
     # decirle a letsencrypt qué certificados adicionales obtener
      - replace:
          filename: "/etc/runit/1.d/letsencrypt"
          from: /--keylength/
          to: "-d www.rpg-foren.com --keylength"
      - replace:
          filename: "/etc/runit/1.d/letsencrypt"
          from: /--fullchainpath/
          to: "-d www.rpg-foren.com  --fullchainpath"
          global: true
cat /etc/runit/1.d/letsencrypt
#!/bin/bash
/usr/sbin/nginx -c /etc/nginx/letsencrypt.conf

cert_exists() {
