Can't install any plugin in netbeans ide 8.1.

I get the following error:

Unable to connect to the Plugin Portal because of Connection reset

Check your proxy settings or try again later. The server may be unavailable at the moment. You may also want to make sure that your firewall is not blocking network traffic.

Or when run Check for updates:

Unable to connect to the Plugin Portal because of Connection reset

Already tried:

  1. Turn off the fire wall
  2. Add the option "-J-Djava.net.preferIPv4Stack=true" to the netbeans_default_options in "\NetBeans 8.1\etc\netbeans.conf"
  3. Run netbeans as System Administrator

What can i do? Please help

Click on Tools -> Options in General tab select No Proxy radio button, if you are not using any Proxy Settings for your Computer. This might be the problem.
