java - LinkedIn - unable to find valid certification path to requested target -


we have several apps working few days ago , today not able log linkedin

the error we're getting is:

org.scribe.exceptions.oauthconnectionexception: there problem while creating connection remote service. sun.security.validator.validatorexception: pkix path building failed: sun.security.provider.certpath.suncertpathbuilderexception: unable find valid certification path requested target

does know why happening , how solve this?

pkix stands "public key infrastructure exchange." cause of server connecting changed ssl certificate chain system doesn't know.

upgrading jdk may fix issue nature of trusting newer root certificate. otherwise, can extract root certificate chain provided or find way, , add trust store.
