Question

Eu recebo a mensagem de erro SSL_ERROR_RX_RECORD_TOO_LONG do Mozilla Firefox quando conecto ao meu site pessoal:

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.

Meu site está hospedado em um servidor VPS, mas estou tentando acessá-lo do meu computador pessoal em casa.

Esta mensagem de erro só acontece imediatamente após eu reiniciar meu servidor VPS. Após a inicialização, se eu reiniciar o httpd.service , o problema desaparece.

Estas são as mensagens relevantes de /var/log/httpd/error_log :

Este é o meu arquivo /etc/hosts :

127.0.0.1 localhost vps

Comando hostname retorna vps .

Meu servidor VPS executa o Arch Linux e apache-2.4.23-1 .

Como posso resolver este problema?

Parece que as diretivas VirtualHost estavam erradas. O caminho certo é:

<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>

A única diferença está nas duas primeiras linhas.

Obrigado ao usuário BtbN do #httpd no Freenode.
