Let's Encrypt creates a certificate for www. but not for .

Hello,
First thank you for ISP Config 3, it really is an awesome tool, we use it every day !

I have a little problem when I create a website on ISPConfig 3.1.6 :
- On Domain Tab : I create a website say example.com, select auto subdomain "www", check SSL and Let's Encrypt, then Save
- On Redirect Tab : I check rewrite HTTP to HTTPS and Save
Let's encrypt creates a SSL certificate for www.example.com but not for example.com (I expected to have both in a single SSL cert).

For now the solution I have found is to create the website without the "www" auto subdomain, then create manually an alias with www (I haven't tested with a subdomain), then LE creates a SSL certificated with both . and www.

Is it an expected behaviour or is there a fix for that ?

Thank you

 

Thank you for your fast answer
I'll try this next week and I'll tell you. (I prefer not to generate LE too often to avoid reaching my quota).
