After I upgrade my netbeans to 8.2 I got an error stack on "Contacting service"

I cannot reproduce it on my side. It looks like a temporary network problem.

Are you behind a corporate firewall / proxy? That may be the cause.

I turn off the firewall and turn on again work fine now.
Nothing change before I upgrade(firewall/proxy)
