i’m trying to make a certificate with certbot (letsencrypt) for my installation (manual) of rocketchat but i struggle.
My certificate need to be on a subdomain and i already have one certificate generated for another subdomain.
How can i generate my certificate to be able to connect to my rocket chat with the ios/android app.
Can someone help?
Thank you in advance.
PS: sorry if my english is bad i’m not an native speaker.
