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

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" />
