各位大神请问一下今天我们域名证书到期更新后，FR设计器远程连接抛错：

com.fr.workspace.engine.exception.RemoteDesignUnknownException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

要怎么解决呀，感谢！！！
