AlmaLinux server unreachable after cPanel install and reboot

[quietFinn]

I have some kind of notworking problem,
I installed AlmaLinux 8, rebooted, OK
I installed cPanel, ran Initial Quota Setup, and rebooted - server unreachable, no network
I connected via KVM, logged in as root and ran "service network restart", and it's back online

I rebooted again and had to do the same.

Hey hey! Could it be this network manager issue? https://support.cpanel.net/hc/en-us...installing-the-cPanel-software-on-Almalinux-8

I've seen that:
" You will need to work with your network or system administrator to configure the server to be compatible with the Network service. By default, this will work with stock images of these operating systems and will only occur if customizations have been made to them. In some cases, you may need to contact your hosting provider for further assistance. "
The hosting provider replied:
"Your request is about the configuration of the service, we're very sorry, but despite we wanted, we're unable to provide support and the confirmation you're looking for."

Was hoping someone would know how to fix that.

I personally don't have any thoughts on that portion on my end, since each host and network can be a bit different.

I have faced the same issue lot of times. You have to add change the network file.

I had problems with quotes with XFS file system so I decided to reinstall this server (OS, cPanel & CloudLinux), also wanted to see if I have learner from the previous installation.

So I reinstalled AlmaLinux 8, now selecting ext4 filesystem,and then installed cPanel.

Right after that I ran: yum remove NetworkManager & rebooted, and after a few minutes the server was back online.
So I didn't need to modify any network settings.
FYI this is an OVH dedicated server.
