title: Cannot connect to tomcat server
body: <p>I am trying to install tomcat in a Ubuntu Server machine.</p>
  <p>At first i installed tomcat8 through <code>apt-get</code> and i was able to connect. Then i tried to add some webapps for <a href="http://dspace.org/" rel="nofollow noreferrer">dspace</a>, and from the time i added them, i cannot connect to the 8080 port. I removed the webapps and still i couldn't connect.</p>
  <p>I already tried to reinstall tomcat, then i manually installed tomcat and i also tried tomcat 7 and 9, but i couldn't resolve my problem.</p>
  <p>I tried to change the port, and I had the same problem. Also there are no other programs using this port.<br/>
  I tried apache server at port 8080 and it works, so there shouldn't be a problem with my provider or firewall.</p>
  <p>Also, the catalina.out log doesn't have any warnings.</p>
  <p>Any ideas before I make a fresh install of the Server?</p>
