我想创建推送通知服务器,并在服务器中安装SSL证书和.p12文件时,我们面临以下错误：我想知道ssl证书有什么问题,因为我收到certificate_unknown错误.

main, RECV TLSv1 ALERT: fatal, certificate_unknown

main, called closeSocket()

main, handling exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown

Error pushing notification(s):

Invalid certificate chain (Received fatal alert: certificate_unknown)! Verify that the keystore you provided was produced according to specs...
