we are using the version 3.2.0 of twitter4j library. Since 14. october we have the problem with the authentication. The error message is “Caused by: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated”.
After update the twitter api to the version 4.0.2, we get the following error message: “Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target”.
Can you give us some tips to solve this problem?
