我正在尝试通过VncViewer（TigerVnc）连接x11vnc服务器。我给以下命令以-ssl选项启动vnc服务器
$ x11vnc -ssl -rfbauth /home/root/.vnc/passwd
当我尝试连接vnc服务器时，出现TLS握手失败错误。
以下是vncserver日志

这正常工作，没有错误。唯一的更改是openssl版本，它已从OpenSSL 1.0.2p（2018年8月14日）更改为OpenSSL 1.1.1d（2019年9月10日）。
我检查了OpenSSL 1.1.1d是否支持TLSv1.3和TigerVNC支持TLSv1.2，是否由于SSL版本中的版本不匹配而导致错误？
