Playstation 4 NW-31250-1 Error

All my Playstation 4 downloads were failing today with “DNS Error” and “NW-31250-1”.

I ran a tcpdump on my router and found this:

15:07:10.389761 00:ee:ff:aa:bb:cc (oui Unknown) > 11:22:33:44:55:66 (oui Unknown), ethertype IPv4 (0x0800), length 109: (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 95)
    red-death-router.porkrind.org.domain > 10.0.0.113.49218: [bad udp cksum 0x15cb -> 0xfee5!] 21068 ServFail q: A? ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net. 0/0/0 (67)

That looks promising, a DNS SERVFAIL response to a query for “ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net” (whatever that is).

My router is set up to use Google’s DNS: 8.8.8.8. So a quick test from my computer showed:

$ dig @8.8.8.8 ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net

; <<>> DiG 9.8.3-P1 <<>> @8.8.8.8 ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net
; (1 server found)
;; global options: +cmd
;; Got answer:

“status: SERVFAIL”! But when using Level 3’s venerable 4.2.2.2:

$ dig @4.2.2.2 ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net

; <<>> DiG 9.8.3-P1 <<>> @4.2.2.2 ic.8e0b5f0d.0c2f0f.gs2.sonycoment.loris.llnwd.net

Aha, it works! So Google’s DNS is broken!

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—just clicked retry and they continued from wherever they were.

  1. @Mitch, I don’t remember precisely (I wrote this 2 years ago), but I suspect I left my router’s default (8.8.8.8) as the primary.

  2. BTW, this is coming up a lot today because there is an ongoing massive denial of service attack against DynDNS, which Sony uses for a lot of Playstation network stuff. So everything is just broken today until the attackers stop, or Dyn can mitigate the attacks. 🙁

    See https://www.dynstatus.com/incidents/nlr4yrr162t8 for the status on the attack.
