I was tempted to ask you this on the comments but I thought I could elaborate more in the answer section with a potential fix.
So, when you have a connection refused on any service, not just Chef, check that the service is doing what it should be. So I assume you took apache 2.x cookbook and installed it correctly, yes?
Stage 1:
If so, issue:
netstat -anp | grep :443 # or whatever your designated HTTP/HTTPS port is.
and if you see it, great, service is running and has opened the port, proceed to Stage 3. If the service hasn't opened the port, proceed to Stage 2.
Stage 2:
Make sure that you either configure SELinux to allow for a service to spawn-open a port.
https://wiki.ubuntu.com/SELinux
and then;
semanage port -a -t http_port_t -p tcp 443
You can always check if SELinux is enforcing or disabled in the SELinux configuration file.
If SELinux is disabled, then check whether you have iptables running and if so, issue the command (assuming port 443 is your HTTPS port):
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
or if you use firewalld
firewall-cmd --zone=public --add-port=443/tcp --permanent
Stage 3:
Do you have permission to view the directory /users? You did not specify an HTTP error number, so I assume that whatever you are trying to do is refusing the connection, possibly due to permissions.
Remember that the Chef command you are using is trying to create a user, you could try sudo if you're not root also!
Another error that could be possible is checking your SSL settings and making sure that you have allowed 127.0.0.1 to be viewed by 127.0.0.1.
Apache 2.4 has different rules and not the old fashionable "allow order"
You could test with this to see if it works:
<RequireAll>
Require host address #Change as necessary
Require ip ip.address #Change as necessary
</RequireAll>
i.e.:
<RequireAll>
Require all granted
Require not ip 10.252.46.165 # This denies IPs
</RequireAll>
Finally, if none of this works, then check your httpd log files, they are your last resort...well...google is..
