Question
Solr and Tomcat Connection Hangs Forever
- Posted November 17, 2014
Hi
I’am trying to login Solr admin for “pointro” droplet. via :8080/solr but it hangs no response at all. So is any firewall setup present?
Because at first install, everything worked, but now suddenly stopped.
I follow this steps descibed in this document;
What is the workaround?

That is a fairly common problem. By default, Tomcat will prefer the IPv6 address. You’ll need to force it to use IPv4 by setting -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true in your JAVA_OPTS
You can add those values to JAVA_OPTS in the file /etc/default/tomcat7 and the restart Tomcat with: sudo service tomcat7 restart

Just discovered, tomcat running on tcp6, netstat -tapen | grep “:8080”
But other spawed foreman processes (i.e puma) running on tcp? Is that diff cause this issue?
