yum update breaks CentOS

Question

There is a CentOS 7 VPS. I just tried to follow guide to install php 7.4, and ran

sudo yum update

It did stuff, outputted a list of "install" lines, and then a list of "clean" lines, as I remember, like

clean something (82/82)

Comes to 82, and seems to hang, it did not exit, although input was working. I tried to enter exit, sudo exit, sudo reboot, but it just entered and no result.

Earlier I set up Apache, ssl, all worked. I rebooted VPS, and now my site does not work as from domain as from IP. It says connection refused.

I also now can't connect via ssh (timeout error), but can connect via VNC.

Ssh stopped work before reboot - when in current powershell window with ssh session hanged (i.e. hanged yum update command, as I described above), I closed powershell, and opened new one, but already could not connect.

Can my server be restored?

Update

Try to follow this one answer. Is this output ok?

output of sudo firewall-cmd --list-all ,

sudo systemctl status sshd

Says that it is active

Update 2

Seems like I removed ssh service in firewall. Now I reinstalled firewall, added ssh, and I can connect via ssh.

But I still get connection refused, trying to open site in the browser.

Answer 1

So basically, there was two issues:

1. SSH - Following Digitalocean guide on firewall setup, I just copied all commands, without reading the descriptions and run command that blocks ssh with firewall. I reinstalled firewall, setup it again, without calling that command and now can connect via ssh.
2. HTTP - seems like I just skipped command to run httpd on boot: sudo systemctl enable httpd.service

Now all works. Why it broke on yum update I do not know for sure.
