nginx server block configuration not working
I'm a teacher at a school are we are trying to setup a Centos 7 Nginx server to host the kids work while they learn.
We followed the tutorial here at https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-server-blocks-on-centos-7
When we complete the setup, we get a "Welcome to nginx!" page instead of the example page we created for testing.
We have gone over the configuration and googled around for about an hour, we'd really like to get this up before the kids are back on Monday.
Can anybody help us please, and what conf files do you need us to post to assist in the troubleshooting.
Thank you =)
