Check your firewall configuration:

sudo firewall-cmd --get-active-zones; sudo firewall-cmd --list-all

Firewalld uses nftables backend by default since Fedora 32:

sudo nft list ruleset

Hello, Vladislav!

Thank You! Did not know.

This nothing no change. You may install openssh-server and to verify, port tcp 22, not closed.

Yep, SSH is supposed to be open in the default configuration, but you can close it:

sudo firewall-cmd --permanent --remove-service=ssh
sudo firewall-cmd --reload

That’s the point.
