automationhub_admin_password='password'

automationhub_pg_host=''
automationhub_pg_port=''

automationhub_pg_database='automationhub'

I think I fixed it! I went and made sure:

yum remove httpd
yum remove nginx
yum remove postgresql
yum remove redis
yum remove pulpcore-selinux

cd to /var/lib/

rm -rf pgsql, nginx, redis, containers, private pulp, redis

rerun ./setup.sh

wait

when its done check nginx

if you see the error below I removed the duplicate default deferred server.

restarted nginx.

nginx healthy.

There can only be one default server for each port not for the same port number example below in the automation-hub nginx.conf file

server {

listen 443 default_server deferred ssl;
# listen [::]:443 default_server deferred ssl;

server {
listen 80 default_server;
# listen [::]:80 default_server;

Systemctl restart nginx should show:

Just wanted to say thank you for this solution! Saved my team a bunch of time and headaches during our Ansible Tower to AAP data migration.
