Identifying the problem

In most cases, every website stores information about the errors that occur when it is accessed and a visit’s details (the address it was accessed from, how many times, what browsers were used, etc.). All of this information is stored in the server’s log files.

If the site does not open, log in to the server and view the information about the website errors in the log file. It is stored in different places on the hard disk in each operating system:

Log file of website errors

FreeBSD: /home/httpd-logs/<your_site>.error.log

Debian/Ubuntu/Centos: /var/www/httpd-logs/<your_site>.error.log


Log file of Apache errors


FreeBSD: /var/log/httpd-error.log

Debian/Ubuntu: /var/log/apache2/error.log

Centos: /var/log/httpd/error_log


Log file of Nginx errors



Debian/Ubuntu/Centos: /var/log/nginx/error.log

The “Server Not Found” Error

A possible reason for such an error is that a user does not get redirected to the web site’s IP address by its domain name. This occurs due to DNS problems, you will need to perform diagnostics of the nameserver.
