Letsencrypt with multiple domain in one certificate

[baoc75]

Hello,
Assume that I want to generate SSL certificate for www.abc.com and abc.com. I will type into the domain fields as www.abc.com,abc.com. Certbot still understand that, but the cert concat process will include the comma "," which makes the file won't work anymore thus the certificate won't saved in /etc/ssl/certs.
Now if I generate one by one then it will be stuck as certbot ask whether I want to update the existing one by press "Y"

Hello,
If delete wrong certificates, will it work?

We will investigate about comma

[baoc75]

It won't work because it can't write to filename with comma character. When I open that file www.abc.com,abc.com.pem, it exist but is an empty file. The app also throw errors too (definitely not related to Certbot as the cert already created)

[Aidaho12]

No, I meant does it work for one certificate?

[baoc75]

Oh it works very well if you generate certificate for 1 domain like "abc.com".
