🔧 Verified Fixes for WS-37397-9 (Playstation)

Restart your ISP modem/router and keep it powered off for 10 minutes to obtain a new dynamic IP.

Contact your internet service provider and request an IPv4 pool refresh or static IP.

Test connection via mobile hotspot to verify console hardware is unaffected.

🚫 What Will NOT Help During an Upstream Outage

If Playstation servers are experiencing an active disruption or maintenance window, performing unnecessary destructive changes to your equipment will not resolve connection failures:

Reinstalling or deleting the application: Server authentication and handshake errors reside on platform infrastructure, not your local game files.
Factory-resetting your router or modem: Power-cycling is safe, but resetting router firmware to factory defaults will not bypass cloud gateway errors.
Submitting ISP line complaints: Upstream provider outages affect all internet providers equally and cannot be resolved by consumer ISP technicians.
