Hi there,
I just followed your guides and it still to be offline after what I did. Here is my screenshot.
1 : SSL.
2. DNS, my Nameservers remained from my domain provider. I just used recommended.
3. Server IP Address.
4. IP Address. VirtualBox connection and I'm using NAT.
5. IP from my router.
6. Port forwarding.
7. Apache2 live.
8. My configuration. I just overwrote from the earlier configuration that you posted.
9. SSHD Config.
10. UFW Status. I just added 8888 port.
11. Website aurax.site.
I'm not sure what is wrong. Are there any commands that I missed?
