@NashBrydges Yep, changed it to yes and now I can access via SSH!!! Thank you for the help!
Good man! You got the job done!
If the ssh server is accessible from the internet make sure the root password is long enough and random. At least 16 characters preferably.

@Pete-S No external access so they are golden. Password has been changed to a 20 character one as well.

Make a new user for this and disable root in
sshagain anyway. -

The previous IT guy set it up on Fedora and added Webmin. I was told that there was no new password selected for Webmin and that it would login as root so he gave me the access password and in fact I can login to Webmin using root + password however, when I try to login through SSH using the same credentials, I get an Access Denied error.
Root is disabled by default in SSH configs most of the time.

I ran sudo pwck -r /etc/shadow and I get this output related to root user.
sudo pwck -r /etc/shadow
invalid password file entry
delete line 'root:$6$wMHG.3SSWjCcHHKO$9UmPtJcSyKaA/EKLWX6vhx02eaJH7yfdsDA9PRCadROMMb6Sgjggdq7V0/gNXB3q19LZK.sYshPiEyv3XYv8D.::0:99999:7:::'? Noroot isn't impacted by sudo

@Dashrender I thought that too but when I enumerate users...
cat /etc/passwdI get this for root...
root:x:0:0:root:/root:/bin/bashUnless I am reading this wrong, it doesn't look like that was the case. There are also no other users listed in the output besides the apache, mysql, systemd...etc.
It's the SSH config, not the password that is the issue. You know the /etc/passwd file is working great since WebMin is using it and verifying that for you. So you know the issue is limited to SSH.

This is expected behaviour. The former IT just didn't change it. They might have installed WebMin because they didn't know how to do this. WebMin is a pretty weird thing for an IT shop that knows Linux to install. So my guess is that they were so lost that they attempted a workaround.

Switch to a key

Not until the last couple years. Sure we always disabled it, but it was not default that way until recently.

Ubuntu disabled it by default in 14.04 (2014) and Debian in version 8 (2015).
This probably coincide when openssh developers decided that disabled should be the default in the source code.
It's up to the distro to set defaults for installed packages so RedHat based distros like Fedora might have been much later.
