Hi,
Please run curl with the --trace trace.txt and upload the trace.txt file here, so we can see if TLS or a version of SSL is being used to connect to the server.
Also, you may need to add the server certificate to the JVM cacert file by doing the following:
keytool -import -alias <alias> -file <cer> -keystore {Ready API install}\jre\lib\security\cacerts -storepass changeit
where <alias> is the certificate alias in truststore (any string value, e.g. MyServer_cert)
<cer> is the filepath to the cer-file.
The keytool can be found in {Ready API install}\jre\bin directory.
If you have any troubles with the keytool utility, you can use Portecle or any similar utility with GUI. The following video shows how you can import a certificate using Portecle: http://www.screencast.com/t/bfx3RRt71Hgl
