So a quick test from my computer showed:<\/p>\n “status: SERVFAIL”! But when using Level 3’s venerable 4.2.2.2:<\/p>\n Aha, it works! So Google’s DNS is broken!<\/p>\n To fix this I set up my PS4’s networking manually and added 4.2.2.2 as a secondary DNS server. Then all my downloads started working again. I didn’t have to delete them and start over, either\u2014just clicked retry and they continued from wherever they were.<\/p>\n","protected":false},"excerpt":{"rendered":" All my Playstation 4 downloads were failing today with “DNS Error” and “NW-31250-1”.
