Hello, when I check the nginx error log I notice that alert and I don’t know why, I cannot access my website from http or https, my DNS in cloudflare are: 

A - mydomain.com - MY IP
CNAME - www - mydomain.com

Hi there @hcmendez,

It most likely means that you have your mydomain.com domain specified in multiple Nginx server blocks.

What you could do is use the grep command and search for the mydomain.com domain inside your /etc/nginx/sites-enabled folder:

  • grep -r mydomain.com /etc/nginx/sites-enabled

If you see the domain name in more than server blocks for port 80, you would need to remove the duplicate one and then restart Nginx.

Hope that this helps!
Regards,
Bobby
