Nginx server times out on ports 443 and 80

Question

So my problem is the following. I am using CentOS 7.8 and I installed nginx, php, mariadb and certbot. After successfully generating the SSL certificate certbot automatically overwrote the NGINX config file (well I did agree to that and it usually works). I looked at it and nothing seems to be wrong with it. What's the problem? Firewall has ports 80 and 443 open... There are no other virtual hosts setup... My partly automatically generated and partly automatically appended nginx config:

A timeout usually points toward a firewall issue. Just because you disabled one that doesn't ensure that there isn't another one blocking traffic between you and your server. — Gerald Schneider, Oct 27 '20 at 14:00
@GeraldSchneider The software firewall is disabled at the moment and the hardware one has ports 80 and 443 open... — Munchkin, Oct 27 '20 at 14:06
nginx configuration doesn't cause timeouts, so the problem is somewhere else. — Tero Kilkanen, Oct 27 '20 at 15:57
nginx -T && iptbales -S && netstat -tulpn && cat /var/log/syslog --- some commands to start with. you may poste the output here. — Berndinox, Oct 27 '20 at 19:06
I reinstalled the server and everything worked fine, but this time I used Apache. Not sure what the issue was, maybe the disabled and marked `firewalld` ? — Munchkin, Oct 28 '20 at 14:26

I had same issue with one of my server. Client was using hardware firewall and complex NAT. Please try to do below things.

Try to disable firewall(software/hardware)
Check Server IP configuration
