I have some simple code that does what I think is a correct & basic request to read the url https://httpbin.org/digest-auth/auth/user/passwd
Reading that url in a browser works fine. But the code throws: Exception in thread "main" 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 sun.security.ssl.Alerts.getSSLException I have the code and full exception stack at http://stackoverflow.com/questions/43146218/https-digest-request-failing-with-security-exception (not repeated here to keep this email short). Any ideas? Thanks - dave
