I move all my sites to a bigger vps (the 2 vps are with Debian 8 & Virtualmin). How do I need to do for the Let's Encvrypt ssl ? Revoke from the 1st server and how to ?
Here's the beginning of the error that I get on new server when I ask for Let's Encrypt ssl: Parsing account key... Parsing CSR... Registering account... Already registered!
