Let's error on server with Plesk panel

Hi all!
On my VPS CentOS server from OVH, I have Plesk Obsidian control panel to manage some domains.

For these domains Let's Encrypt certificate are ok, not for my server (host name is "exciting-banach.51-75-93-252.plesk.page"), I don't know to solve continue error, and I think host name now is on any black list.

Have you some suggests to solve this issue?
Thanks!

Max.

Hi @Max_sec, and welcome to the LE community forum :slight_smile:

Let's find out if the IP is blocked or not, with:
curl -v4 https://acme-v02.api.letsencrypt.org/directory
