We use a certificate for our webservice connection with Van Ameyde. This certificate is added in advanced settings/Custom Mendix settings. This worked fine, but after a new deployment we get a certfication error see below: HTTP transport error: 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 at com.sun.xml.ws.transport.http.client.HttpClientTransport.getOutput(HttpClientTransport.java:132) at com.sun.xml.ws.transport.http.client.HttpTransportPipe.process(HttpTransportPipe.java:256) at com.sun.xml.ws.transport.http.client.HttpTransportPipe.processRequest(HttpTransportPipe.java:184) at com.sun.xml.ws.transport.DeferredTransportPipe.processRequest(DeferredTransportPipe.java:137) The path is correct. What can be wrong here?
