Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:carle.co.in

I ran this command: generation from plesk windows

It produced this output:
Could not issue an SSL/TLS certificate for carle.co.in

It looks like your server is not able to connect to the Let's Encrypt server. What happens when you do this from a command prompt:

curl -I https://acme-v02.api.letsencrypt.org/directory

its not opening from curl -I https://acme-v02.api.letsencrypt.org/directory
but from start https://acme-v02.api.letsencrypt.org/directory

I don't know why Plesk would issue the error you reported:

It looks like you can reach the LE server (with start anyway) and I can reach your server just fine. Maybe ask about this on a Plesk Forum. They even have one for older versions:

Is there any curl there anywhere?
dir c:\curl.* /s

6

ok
i will discuss on plesk forum

7

No
there is no curl anywhere

that's strange. I have curl.exe on windows 11.

There was also this announcement that Let's Encrypt is blocking Plesk as an emergency measure; I haven't seen any followup saying that they re-enabled it but I may have just missed it.

Might not be related to your issue, though.

Thanks for the reminder! It's been unblocked since about a day after that announcement.

Recent versions of Windows ship with curl, old ones didn't. Incidentally Server 2012 only has about 1 year left before it doesn't get updates anymore, so anyone using it should migrate to newer versions as soon as practical.
