Can anybody help me with this?

I am working on a HTTP Get call and get the following error in the system error log:

Wrapped javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Example of the code:

var url = 'ultra.fobocloud.com/.../vehicle
var result = rbv_api.sendHttpGet(url);
rbv_api.print(result);

I already checked this post but i cant get any further with this
