I am trying to implement the LEscript.php library (https://github.com/analogic/lescript) on our server to automate the renewal process. When running the script for any domain, I receive the above named error message, but as I am pretty new to LE, I not really understand where to look for the solution.
Maybe someone can get me some advice? What does this message exactly mean, and what should be done to solve it?
I manually created a first certificate (for a different domain) using the https://gethttpsforfree.com/ website (this worked very well!!!), so I belief LE should have my email address and certificate details.
