NP-34957-8 blocks PSN sign-in during outages or strict NAT. Compare with NW-31201-7 fixes.
NP errors after PSN maintenance
Sony maintenance often clears without console action — wait 30 minutes after status returns green.
DNS and network optimization
Change DNS to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) on your console or router. Stale ISP DNS caches cause NP- and 0x errors after platform maintenance. PS5: Settings → Network → Settings → Set Up Internet Connection → DNS Manual. Xbox: Network Settings → Advanced → DNS Manual.
WiFi band and wired ethernet
Connect via 5GHz WiFi band instead of 2.4GHz for lower latency, or use wired ethernet for the most stable connection. Console downloads and online verification fail more often on congested 2.4GHz bands shared with smart home devices.
Safe Mode rebuild and license restore
PS5 Safe Mode → Rebuild Database fixes corrupted system files without deleting games. Also try Settings → Account Management → Restore Licenses after network fixes. Xbox: hold power 10 seconds, clear persistent storage in Blu-ray settings, then restart.
Wired ethernet for downloads and auth
Platform downloads exceeding 50GB and license verification during peak hours fail more often on WiFi. Wired ethernet eliminates packet loss that triggers NP-104602-3 and similar codes during PSN or Xbox Live auth checks.
