Certificate Expired on Mail domain

The log is a bit old and the authorization to view the results has expired so I can’t view the real reason you couldn’t renew the certificate.

Anyway, try this fix:

sudo su -
cd /usr/local/hestia/bin/
mv v-add-letsencrypt-domain v-add-letsencrypt-domain.original
wget https://raw.githubusercontent.com/hestiacp/hestiacp/64210fd8ccee8718a861856e99f9965e40ff3932/bin/v-add-letsencrypt-domain
chmod +x v-add-letsencrypt-domain

And try to issue the certificate again.
