proxyNameandproxyPortare incorrect in your<install-directory>/conf/server.xmlfile.

<Connector port="8090" connectionTimeout="20000" redirectPort="8443"
maxThreads="48" minSpareThreads="10"
enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
protocol="org.apache.coyote.http11.Http11NioProtocol" />If you are using a reverse proxy, make sure the the proxyName and proxyPort attributes have correct values for your reverse proxy. Your connector should look similar to the example below:

maxThreads="48" minSpareThreads="10"

protocol="org.apache.coyote.http11.Http11NioProtocol"
