Eu encontrei o problema
ServerName example.com:443
estava faltando na configuração ssl.conf
Por favor considere dois comandos curl :
curl -v --ssl link
* About to connect() to example.com port 443 (#0)
* Trying 10.20.30.40...
* connected
* Connected to example.com (10.20.30.40) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: none
* SSLv3, TLS handshake, Client hello (1):
* error:14077458:SSL routines:SSL23_GET_SERVER_HELLO:reason(1112)
* Closing connection #0
curl: (35) error:14077458:SSL routines:SSL23_GET_SERVER_HELLO:reason(1112)
curl -v -3 --ssl link

Parâmetros:
-v = verbose --ssl = use SSL -3 = use SSLv3 A pergunta é: por que tal SSL23_GET_SERVER_HELLO:reason(1112) de erro? Como corrigi-lo? É o problema de cliente ou servidor (servidor https)?
Eu não me importaria de usar o curl com o parâmetro -3 , mas o mesmo problema aparece ao usar a função file_get_contents() do PHP. Eu sei que existem soluções alternativas do PHP, mas quero fazer as coisas corretamente.
