You get one of these three error messages:

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL
cURL error number:60
curl: (60) SSL certificate: unable to get local issuer certificate
It is likely that the problem is related to a lack in server configuration at the SSL security settings.
It is possible to make sure of it by following these instructions;
1. Activate the Expert Mode
2. Once activated, go to the advanced parameters of the module;
3. Then check the “Disable SSL Check” option like this;
If the module works again in this configuration, contact your hoster for an audit of the SSL parameters.
The module must be able to establish a connection to Amazon with Root Certificates.
