ValidatorException: PKIX path building failed

I’m receiving the following message when I send to the test site and the main registration site: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I haven’t seen this error message before and I’ve registered more than 3000 DOIs. Is this a temporary issue, or do I need to update my code to connect to your system. Thanks,

Mike

Hi @mpalmquist ,

Thanks for your message. We did update our certificates yesterday for *.crossref.org and *.eventdata.crossref.org. If you are still receiving these errors, you should consider updating your local certificate library to include the letsencrypt root certificate.

My best,
Isaac
