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

I had the same problem with the certificates error and was because of SNI, and http client that I used didn't had SNI implemented. So an version update did the job

   
        org.apache.httpcomponents
        httpclient
        4.3.6
