Tomcat HTTP redirect issue

Hello,

I had tomcat configured to redirect any requests to HTTP to redirect to HTTPS. This was functioning well until we had to do a DR restore of the DEV application. Now, HTTP does not redirect, but HTTPS works fine. I have compared the web.xml and server.xml configurations between our DEV and PROD installations, and found no differences. Below are the sanitized versions of the config:

Server.XML

<Connector port="80"
                   maxThreads="150"
                   minSpareThreads="25"
                   connectionTimeout="20000"
                   enableLookups="false"
                   maxHttpHeaderSize="8192"
                   protocol="HTTP/1.1"
                   useBodyEncodingForURI="true"
                   redirectPort="443"
                   acceptCount="100"
                   disableUploadTimeout="true"
                   bindOnInit="false"/>


<Connector port="443"
				   maxHttpHeaderSize="8192"
				   maxThreads="150"
				   minSpareThreads="25"
				   maxSpareThreads="75"
				   enableLookups="false"
				   disableUploadTimeout="true"
				   acceptCount="100"
				   scheme="https"
				   secure="true"
				   SSLEnabled="true"
				   clientAuth="false"
				   sslProtocol="TLS"
				   keyAlias="DEV_ALIAS"
				   keystoreFile="L:\ocation\to\keystore.jks"
				   keystorePass="supersecretkey"/>

Web.XML (this code is entered after all of the servlet-mapping, and before filter-mapping)

security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>

Any idea why this might be failing?
