Trying understanding LetsEncryt setup in Plesk


thanks for prompt help received. With every case it still seems unclear to me how LetsEncript has to be setup in Plesk. For example my domain is not catching with https in the meantime again and steps are a bit cunfusing for me.

Questions are :
? a) which certificates are being created or requested (not sure what happens) at which step of establishing a domain or sub-domain in Plesk ?
? b) are there any differences in certificates that can be auto-created / requested ?
? c) why are there many LetsEncrypt certificates automaticaly created in Plesk, one for each domain or sub-domain that had been setup for LetsEncrypt ? Can’t there be only one LetsEncrypt certificate for all domains and sub-domains i use ?
? d) Why are such multiple sub-domain LetsEncrypt certificates being offered to select from in LetsEncrypt setup in Plesk for another domain or sub-domain ? I have deleted them out now to unclutter.
? e) Why did the LetsEncrypt for not install ?

? f) What role plays the email address requested in the process ?
? g) which LetsEncrypt certificate is the right pick from many offered LetsEncrypt certificates and why ?
? h) if setup is correct, how long does it take for https to be updated online ? Seems it takes a while.
? i) What does (other repository) mean ?


My domain is:

I ran this command:

It produced this output:

My web server is (include version): Plesk last version

The operating system my web server runs on is (include version): Debian 8.1

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):



I really think those are questions specific to plesk, hence you might want to ask it on Plesk community directly.

Email Address in this process (normally) are send to Let’s Encrypt for Expiry notification emails and emergency contact purposes.

Thank you
