How to create a SAN cert?

Thanks for the quick response Schoen. I used the following commands in command prompt on windows locally on my desktop, then uploaded the files and key generated manually to my host provider. I used:

  1. pip3 install manuale 2. manuale register yourname@gmail.com 3. manuale authorize example.com ■ Add the shown DNS record to your domain 4. manuale issue example.com --output certs

I did the above but added in www. before our domain. I was going to try and simply add ‘and domain.com’ next to the www. above but not sure what to do.
