unable to connect

Question

Hi everyone,

I configured my server yesterday, and today I got “Unable to connect” message. I followed the one click WordPress install tutorial.

I got this message:

Firefox can’t establish a connection to the server at 128.199.207.182.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

So I performed:

1). Apache’s error.log, and got this message:

root@wordpress-1gb-sgp1-01:~# tail -50 /var/log/apache2/error.log
[Sat Dec 09 14:34:33.070859 2017] [mpm_prefork:notice] [pid 1738] AH00163: Apache/2.4.18 (Ubuntu) configured -- resuming normal operations
[Sat Dec 09 14:34:33.071034 2017] [core:notice] [pid 1738] AH00094: Command line: '/usr/sbin/apache2'

2). System Logs, and got this message:

root@wordpress-1gb-sgp1-01:~# tail -50 /var/log/systemlog
tail: cannot open '/var/log/systemlog' for reading: No such file or directory

3). PHP Logs, and got this message:

root@wordpress-1gb-sgp1-01:~# tail -50 /var/log/php*.log
tail: cannot open '/var/log/php*.log' for reading: No such file or directory

I run top as well and got this:
