Let's Encrypt changed its own server SSL certificates used to communicate with their API endpoints in December 2020.
Production - API Endpoint: https://acme-v02.api.letsencrypt.org/directory
Staging - API Endpoint: https://acme-staging-v02.api.letsencrypt.org/directory
This may result in Let's Encrypt 4 Domino (LE4D) no longer being able to communicate with the API during agent execution for certificate updates.
The reason for it is, that the Let's Encrypt root / intermediate certificate are no longer trusted.
