I want to move my cPanel installation from old server to a new server. Because my old server runs on CentOS.

So, I just fresh install Ubuntu Server 20.04.5 on VMWare (New Server). Then I change my hostname, using hostnamectl set-hostname, after that I just go straight install cPanel, using this command

cd /home && curl -o latest -L https://securedownloads.cpanel.net/latest && sh latest

After some period of time, the installer shows a message:
(FATAL): The installation process was unable to synchronize cPanel & WHM. Verify that your network can connect to httpupdate.cpanel.net and rerun the installer.

Actually, few weeks ago I tried install cPanel on Ubuntu with the same step. But I got the same error and at that time I use AlmaLinux because I can't install on Ubuntu

I tried:
ping httpupdate.cpanel.net
PING httpupdate.cpanel.net (103.17.8.8) 56(84) bytes of data.

Well, I'm the Administrator of the Data Center.
I already tried using my other Internet Provider, but still get the same error on Ubuntu (Ubuntu 20.04, Ubuntu 20.04.04, Ubuntu 20.04.05).
But I can install cPanel on Alma Linux, CentOS without issue.

I already submit a ticket #94507529
@ventustium - that looks good. I'm not sure why the installer is having connection issues based on that output. Can you contact your hosting provider or datacenter to have them check things on their end? You can also submit a ticket to our team and we can take a look.
