Failed to enable crypto

[shinesoftware]

Hello guys,

I get this error:

installer_1      |   [Composer\Downloader\TransportException]                                                                                                    
installer_1      |   The "https://packages.firegento.com/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:

installer_1      |   Failed to enable crypto                                                                                                                     
installer_1      |   failed to open stream: operation failed  

Why this happens? Is the SSL module installed at the container?
