I'm trying to create an SSL certificate, following the video of the TMS channel on youtube: https://www.youtube.com/watch?v=gsYgV8zIcQg&t=481s
I followed the same steps as the beginning of the video, installed lets encrypt, when I put my email, an ACME error was returned, as shown in the image.
It's the same process. The new version might have small different things, different names maybe, but the process is exactly the same. The new version is actually even more friendly.
Follow the process of generating a certificate as usual, and when the tool asks you for a script to be executed when the certificate is generated, use the exact same script and parameters described in the blog. That part stays the same.
