Let's encrypt certificate not auto-renewing (4372422)

With the need of securing the traffic and data of the SMA adding a SSL certificate is a highly recommended action but there might be occasions were a CA root cert is not available and adding a Self-Signed cert is not enough, reason why on version 13.0 Let's Encrypt SSL Integration was introduced in order to provide a free integrated alternative for SSL certificates.

The Let's Encrypt SSL certificate only last for 90 days so it needs to be renewed when it gets expired.

The SMA has a built-in script that runs on the backend days before the expiration day comes in, but in some situations it may fail to renew, causing the box to be unable to auto-renew the SSL cert.
