Don't see gitlab ce front page after server restart

New to gitlab ce ,
Installed it in my centos7 LAMP server,
Everything worked great than I restarted my server and the gitlab is not loading anymore,I see the Apache page though…
I did gitlab-ctl start
this is the outcome
ok: run: alertmanager: (pid 3729) 1s ok: run: gitaly: (pid 3737) 0s ok: run: gitlab-monitor: (pid 3748) 1s ok: run: gitlab-workhorse: (pid 3751) 0s ok: run: logrotate: (pid 3759) 1s ok: run: nginx: (pid 3773) 0s ok: run: node-exporter: (pid 3777) 0s ok: run: postgres-exporter: (pid 3781) 1s ok: run: postgresql: (pid 3786) 0s ok: run: prometheus: (pid 3789) 1s ok: run: redis: (pid 3803) 0s ok: run: redis-exporter: (pid 3808) 1s ok: run: sidekiq: (pid 3813) 0s ok: run: unicorn: (pid 3818) 0s

than I did gitlab-ctl status
and it says

What cant be the reason I gitlab is not working

Hey David,

The Omnibus installation comes packaged with Ngnix as the web server, so Apache isn’t needed. It’s likely that when you restarted the server, Apache was started first and thus a port conflict was caused with the Ngnix process.

If you stop and disable Apache, then restart Nginx, does this resolve your issue? This documentation can walk you through disabling Apache on boot for your distro. You can then run gitlab-ctl restart nginx to restart the bundled Nginx instance (you should see an ok output after the command is run).
