Helldivers 2 Failed To Establish Network Connection PS5

✅ What to Check First

Server / PSN status
- The problem might not be on your end. Servers being down or overloaded is a known cause.
  - Check Helldivers 2’s official Twitter / Discord or server status pages.
  - Also check PlayStation Network service status (for issues in “Gaming & Social” etc.).
Restart everything
- Power off the PS5 fully (not just rest mode).
- Turn off/unplug your router and modem briefly.
- After a minute, power them back on, then start PS5 and Helldivers 2. Many users have resolved the error with a full reboot.

Try these one by one (or in combination) until it works:

Fix	How to Do It / Notes
Disable Crossplay	In Helldivers 2 settings → Account & Network (or Gameplay) → turn off Crossplay. Many reports say disabling crossplay helps avoid connection conflicts.
Use Wired Connection	If you’re on Wi-Fi, try plugging an Ethernet cable directly to your PS5 to get a more stable link.
Check / Change NAT Type / Router Setup	Ensure your router settings allow games to connect: enable UPnP, or set up port forwarding for Helldivers (TCP/UDP).
Change DNS	On PS5: go to the connected network → Advanced Settings → DNS → set Google DNS (8.8.8.8 / 8.8.4.4). Some users report this helps.
Update Game / PS5 System	Make sure both the game and PS5 have the latest patches. A mismatched version might block connection.
Check PS Plus / Console Sharing	If your console is using another account’s PS Plus, make sure console sharing is enabled for that account. Some users got the “failed to connect” error due to PS Plus / sharing setup.

Rate limiting / capacity constraints: The devs have acknowledged that “Failed to connect” sometimes occurs when too many login requests occurs in a short timeframe or when the servers hit capacity.
Even with increases in server limits, the error can still resurface during peak times.
