This is a feature that we really needed. Absolutely.

Please add this feature and please give open to add subdomain alias to Let's Encrypt

multilang with subdomain on same host is a pain right now

I actually found that is possible to add a subdomain alias by just Domains > Add Alias > input your alias ignoring the "www." label, like "subdomain.domain.fld". That's it.

@Please include this simple feature!!! @Plesk just need to modify the validation of the form I think, it's a standard option for apache2 and nginx!!!!!!!

Aliases for LE only work if the subdomain is registered as "domain", hence punching up the domain counter.

@Plesk
Please make it possible to add aliases for subdomains by the subdomain definition of Plesk (not DNS definition).
Right now it's only possible to add aliases do "plesk domains" and not "plesk subdomains".

Thanks!

I updated the extension to Let's Encrypt 2.0.0-21 and do not see any options to add aliases. I tried renewing existing domain and also deleting Let's Encrypt SSL and replacing with self-signed and then re-installing Let's Encrypt SSL and still no alias options. I even uninstalled Let's Encrypt extension and re-installed. No joy.

Would adding ServerAlias to the Apache config not do the job here?

This is a simple feature. I hope that made a short time.

Plesk is not a GUI for dig. It is not useful. I will create redirects using my hosting provider panel to not waste precious domains if I haven't unlimited domains Plesk license.

Please add this Feature and recognize alias Domains in Lets encrypt extension

AND: wildcards are impossible! not even with this workaround.

This is the norm in cPanel

I want this feature too!
