Latest outage should now be resolved. Please post PSN ID and region if you encounter additional “Authentication” errors.Ash_2_Dust83 commented
There is a post under "fixed" category from November 29, 2015 for the same problem as now and ND did not respond until December 1, 2015...3 days later. And their response: a server restart. They are not going to respond within a reasonable time frame so I wouldn't expect to play anytime soon. TAKE CARE OF THE CONSUMERS THAT LINE YOUR POCKETS WITH MONEY NAUGHTY DOG!!!!
