Hi,

something is wrong with your certificate configuration in the JDK as indicated by the error message:

sun.security.validator.ValidatorException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to find 
valid certification path to requested target

This Stackoverflow thread provides some pointers.

Hi @saliormoon,

you get:

You cannot even connect to this site from your network and this can have a lot of reasons, e.g. you are behind a proxy and it blocks connections to that host.

I get this when I try to connect with curl:

daniel@io:~ $ curl -v https://developer.nrel.gov
* Rebuilt URL to: https://developer.nrel.gov/
*   Trying 54.164.53.78...
* Connected to developer.nrel.gov (54.164.53.78) port 443 (#0)
* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
* Server certificate: developer.nrel.gov
* Server certificate: Let's Encrypt Authority X3
* Server certificate: DST Root CA X3
> GET / HTTP/1.1
> Host: developer.nrel.gov
> User-Agent: curl/7.43.0
> Accept: */*
>
< HTTP/1.1 200 OK

So I think you need to fix your (Java?) network issues before-hand.

Yes, thanks a lot. I can't access external network and have to use Cntlm to configure some proxy settings. So it's maybe that the proxy settings occur errors.

This problem has been resolved. Thanks a lot.
