Ошибка SSL Tomcat после настройки сертификата

после генерации сертификата и ключа pem-файла с помощью openssl на ubuntu 16.04 я настроил Tomcat connector на сервере.xml-файл, как указано ниже, но, когда я начинаю tomcat я получаю ошибку.

в браузере, когда я ударил этот url:https://localhost:8443/ он дает ниже ошибка:

This site can’t provide a secure connection localhost sent an invalid response. 

команда, используемая для создания сертификата и ключа pem файл, как:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

разъем Tomcat:

<Connector port="8443" maxHttpHeaderSize="8192"
        maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
        enableLookups="false" disableUploadTimeout="true"
        acceptCount="100" scheme="https" secure="true"
        clientAuth="false" sslProtocol="TLS"   SSLEngine="on"   SSLCertificateFile="conf/cert.pem"   SSLCertificateKeyFile="conf/key.pem" />

что-то остальное:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
