I’m trying to create a Smartapp that can collect some sensor data and send it out to my server via HTTPS requests. I have a DigiCert SSL certificate for my server but SmartThings still raised these exceptions:
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.
Any idea how I can make SmartThings talking to my certified server with HTTPS? Appreciate your help!
