I am trying to obtain an SSL certificate from qnap website. My domain is “Marcelinitas.myqnapcloud.com”. But once an again it appears this message:
“No se puede autenticar esta dirección de correo y generar un certificado Let´s Encrypt. Especifique una direccion de correo válida y despues descarga un certificado” The english translation is “This e-mail adress cannot be autenthicated and generate a Let´sEncrypt Certificate. Specify a valid e-mail adress and then download a certificate”
The e-mail adress is “jaboton@gmail.com”, it is my adress and it is required to automatically renew the certificate.
Can you help me please?
