The following certs are not due for renewal yet:
/etc/letsencrypt/live/bigavatar.cubacel.entumovil.cu/fullchain.pem expires on 2020-11-29 (skipped)
/etc/letsencrypt/live/preproduccion.cubacel.entumovil.cu/fullchain.pem expires on 2020-11-11 (skipped)
No renewals were attempted.
Well, almost, August 31th to be exact (for bigavatar.cubacel.entumovil.cu). And it's valid for another 60 days. Your other cert has a few days less, but still more than enough.
Ok, not for *.bigavatar.cubacel.entumovil.cu but for the other.
The documentation does not say that 30 days after the certificate has
been created, it can be renewed?
