AppService call over HTTPS fails saying PKIX path building failed
I have an appservice built in a Mendix App which deployed to an onpremise server which is configured to run over SSL(IIS local) When i now make a call to this appservice from the same app(as a trial run before consuming it in another mendix app) i get the error com.mendix.modules.microflowengine.MicroflowException: com.sun.xml.ws.client.ClientTransportException: 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 ... From the error it seems like while making a call to this service somehow the call should have the digital print of the target system. Anyone has seen this in your scenarios? hints will be great!
It seems that the certificate path is not trusted. You can do 2 things. Use a trusted certificate on your server or trust the certificate path by adding the root certificates in your project/settings/certificate.
In cloud deployments yiu add them to network/Outgoing Connections Certificates
