Cause

The issue can be caused from different issues relating to network connectivity such as protocol not allowed, port not allowed, or firewall blocking the connection.

Resolution

Begin checking if your port is blocked using command prompt and the netstat command to check your port.

If your port is blocked then use a different port or contact your network / security team to unblock the port.

Next, check what Tomcat version and protocol you are using. If you are trying to use a Tomcat version the does not use a supported protocol, then use a different protocol that is supported with the Tomcat version you are using.
Below is the table for protocols to Tomcat version:

	Java Nio Connector NIO	Java Nio2 Connector NIO2	APR/native Connector APR
Classname	AjpNioProtocol	AjpNio2Protocol	AjpAprProtocol
Tomcat Version	7.x onwards	8.x onwards	5.5.x onwards

If options before do not resolve your issue, then contact your internal network / security team to check if anything is blocking access for the connection to take place.

If nothing is able to resolve your issue then contact Broadcom Support.
