Hi guys, I'm trying to issue a Let's Encrypt certificate for the only domain I added in a fresh Ubuntu 20.04 install. Any advice please? Thank you for your time and help.
I am also experiencing problems with Let's Encrypt. Get the following error message: "The remote server returned an error: (400) Bad Request".
Have several domains on the server and the others work fine, but the last domain was added a few days ago, never able to get the ssl to work.
