Hi, I guess the problem is related to this post:
New “bad handshake” & similar errors

Please check if the domain IP is blocked or not @lestaff

My domain is:
Curli
I ran this command:
curl -I -vvvv https://acme-v02.api.letsencrypt.org
It produced this output:

Hi @Alireza-Kiani, and welcome to the LE community forum

@Alireza-Kiani

Please check if the domain IP is blocked

Please post the IP address (not just the domain name).
You can confirm it with:
curl -4 ifconfig.co

There you go: 185.126.200.168

That IP address was blocked; I've now unblocked it for you. If you've had this IP address for a long time, then it's likely that your host was compromised and may need to be rebuilt.
