Hi, can I check your CPANEL configuration please? I'm a server expert and I've faced any kind of issues related to CentOS - Cpanel before, from CGi and Virtualhost errors, to the ones related to CPANEL configuration, I'm a AWS, Azure and Google Console VM Expert so I understand how the VPS works as well.
Let me know if we can discuss your project, I'll be awaiting for your response.
Regards
