Don’t bother asking for help without including the EXACT command you ran and the EXACT error you received.
Fedora is a Desktop OS, not a server OS. Proxmox is ok, but overkill for your needs.
Ubuntu server is what you’re looking for. 12 years of security updates, officially supported livepatch (so no reboots after even kernel updates), and official support.
Hire a professional. This is not a safe thing to do yourself. Any server needs to be professionally secured.
