gitlab-ce on pre-installed nginx server on centos 8 gives 502 error

Question

I am getting the 502 Whoops, GitLab is taking too much time to respond error on my fresh Manual installation of Gitlab-ce 13.2.4 on CENTOS 8 (nginx/1.16.1).

I downloaded the rpm gitlab-ce-13.2.4-ce.0.el8.x86_64.rpm

• dnf -y install policycoreutils-python-utils
• rpm -Uvh gitlab-ce-13.2.4-ce.0.el8.x86_64.rpm
• /etc/gitlab/gitlab.rb >> external_url "https://git.mydomain.com"
• /etc/gitlab/gitlab.rb >> nginx['enable'] = false
• /etc/gitlab/gitlab.rb >> web_server['external_users'] = ['nginx']
• /etc/gitlab/gitlab.rb >> gitlab_rails['trusted_proxies'] = [ '172.16.1.0/24', '192.168.10.0/24']
• /etc/nginx/conf.d/git.mydomain.com.conf >> https://gitlab.com/gitlab-org/gitlab-foss/-/raw/master/lib/support/nginx/gitlab-ssl
• systemctl restart nginx
• gitlab-ctl reconfigure

My git.mydomain.com.conf

My selinux was blocking the url to run. probably the gitlab directory access. I run setenforce 0 and it worked (which is not a good practice though).
