Apache2 closing mysteriously ?

[TGates]

It tells you right here what the problem is:

Code:

apache2: Syntax error on line 224 of /etc/apache2/apache2.conf: Could not open configuration file /etc/apache2/le_tls_sni_01_cert_challenge.conf: No such file or directory

As well as a bunch of other issues. Did you upgrade or customize apache?
Post your httpd.conf file also.
