Netbeans cannot reload the plugins catalog because of connection error

Question

I'm trying to work with netbeans right now and I've run into a bit of trouble with installing plugins and resolving dependencies. Whenever I click the reload catalog button I get an error:

Unable to connect to the Certified Plugins because of Invalid argument: connect

I have proxy settings set to no proxy, have allowed the program through windows firewall, and can not find anything like this anywhere on google.

How should I go about fixing this? Thanks in advance.

Answer 1

I was able to fix it by adding -J-Djava.net.preferIPv4Stack=true into my netbeans.conf file, found deep in the depths of google from this http://netbeans-org.1045718.n5.nabble.com/Newly-installed-NB-7-won-t-connect-to-network-td4672870.html.
