Configurar Let's Encrypt con múltiples dominios / redireccionamientos

[jimkleiber]

So my problem was related to an expired domain name in my multisite configuration:

Let's Encrypt with sub-subdomain?

One of the domains I was using in the multisite configuration was not working because the domain name expired and it was causing an error before the new sub-subdomain was being processed. Once I changed the expired domain name and added an A-record for the new domain name for that, the problem fixed itself.
