I added proxyPort="8080" in /opt/zimbra/tomcat/conf/server.xml, login stil fails with same error.

  <Service name="Catalina">
    <!-- user services connector, no SSL -->
        <!-- HTTPBEGIN -->
    <Connector port="80"
        enableLookups="false" redirectPort="443"
        maxThreads="100" minSpareThreads="100" maxSpareThreads="100" proxyPort="8080" />
<!-- HTTPEND -->
    <!-- user services connector, SSL -->
