Name or service not known: AH00547: Could not resolve host name

Question

I get the SSL_ERROR_RX_RECORD_TOO_LONG error message from Mozilla Firefox when connecting to my personal website:

Secure Connection Failed

An error occurred during a connection to www.fturco.net. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.

My website is hosted on a VPS server but I'm trying to access it from my personal computer at home.

This error message only happens immediately after I restart my VPS server. After boot if I restart httpd.service the problem vanishes.

These are the relevant messages from /var/log/httpd/error_log:

This is my /etc/hosts file:

127.0.0.1 localhost vps

Command hostname returns vps.

My VPS server runs Arch Linux and apache-2.4.23-1.

How can I fix this problem?

Solution

It seems VirtualHost directives were wrong. The right way is:

<VirtualHost *:443>
  ServerName www.fturco.net
  DocumentRoot "/srv/http/www"
  ErrorLog "/var/log/httpd/www/error_log"
  TransferLog "/var/log/httpd/www/access_log"
  SSLEngine on
</VirtualHost>

The only difference is in the first two lines.
