Java: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Question

I have a class that will download a file from a https server. When I run it, it returns a lot of errors. It seems that I have a problem with my certificate

Answer 1

Make sure that the https://176.66.3.69:6443/ have a valid certificate. you can check it via browser firstly if it works in browser it will work in java.
