title: Tomcat 9 SSL/TLS -Failed to initialize component error
body: <p>I have Tomcat 9.0.12 and Java JDK/JRE 1.8.0_191. I'm trying to configure SSL/TLS. I've changed my server.xml file like this:</p>
  
  <pre><code>&lt;Connector port="8080" protocol="HTTP/1.1"
                 connectionTimeout="20000"
                 redirectPort="443" /&gt;
  
  &lt;Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
                 maxThreads="150" scheme="https" secure="true"
                 clientAuth="false" sslProtocol="TLS" 
                 keystoreFile="C:\my_certificate.pfx"
                 keystorePass="my_password" keystoreType="PKCS12" /&gt;
  </code></pre>
  
  <p>My certificate file is *.pfx format. I run tomcat server via command line with startup.bat command. But i got an error like this (in my catalina.log):</p>
