Answer 1

You can try opening the file with Tomcat 8.5\conf\server.xml settings and changing the connector port (the port that tomcat listens on) from 8080 to some other one, for example 8081:

<Connector port="8081" address="0.0.0.0" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"/>
