Tomcat 8.5.51 - Issues with secretRequired="false"

The secretRequired="false" option added to AJP connector is server.xml. However, the connector does not start with Protocol handler start failed error. It is behind an Apache Server version 2.4.25.

    <Connector port="8009"
               address="127.0.0.1" tomcatAuthentication="false" URIEncoding="UTF-8" enableLookups="false"
               protocol="AJP/1.3" redirectPort="8663" connectionTimeout="600000" secretRequired="false" />

The error:

Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.

Thanks

Solution

  • Adding the address attribute and specifying the loopback address is what worked for me on Tomcat 8.5.54.

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" address="0.0.0.0" secretRequired="false" />
