PlayStation Error Code CE-117519-4 — What It Means & How to Fix It

What Does This Error Mean?

CE-117519-4 means your PlayStation 5 cannot connect to an online game session. You may be unable to join a friend's lobby, enter matchmaking, or host an online game. This is a network connectivity issue between your console and the game's online servers.

Affected Models

PlayStation 5
PlayStation 5 Digital Edition

Common Causes

Your NAT type is Strict (Type 3), which blocks peer-to-peer connections needed for online play
The game's online servers are temporarily down or under heavy load
Your home router's firewall is blocking the ports PlayStation needs for online gaming
Your internet connection is unstable — packet loss or high ping causes session failures
PlayStation Network is experiencing a service disruption affecting online gameplay

How to Fix It

Check the PlayStation Network service status at status.playstation.com. Look for any issues listed under 'Gaming and Social' or the specific game you are playing.

If PSN services are down, you simply need to wait. There is nothing to fix on your end.
Run the PS5 network test. Go to Settings > Network > Connection Status > Test Internet Connection. Note your NAT Type — aim for NAT Type 2.

NAT Type 3 (Strict) will cause connection failures in many online games. NAT Type 1 or 2 is needed for reliable online play.
Enable UPnP on your router. Log into your router admin page (usually 192.168.1.1 or 192.168.0.1), find the UPnP setting, and turn it on. Restart your router afterward.

UPnP allows your PS5 to automatically open the ports it needs for online gaming. This is the easiest way to fix a strict NAT type.
Restart your router and modem by unplugging them for 60 seconds, then reconnecting the modem first. Wait for it to fully connect, then plug in the router.

This refreshes your network and clears any routing issues. Many connection errors resolve after a full network restart.
Try using a wired ethernet connection instead of Wi-Fi. Connect an ethernet cable from your router directly to your PS5 for a more stable and faster connection.

Wireless connections can have higher latency and packet loss, which causes CE-117519-4 during online sessions.

When to Call a Professional

CE-117519-4 is a network issue and does not require a repair technician. If you have tried all steps below and the problem persists, contact your internet provider to check your connection quality. For game-specific server issues, contact the game publisher's support team.

Frequently Asked Questions

What is NAT Type and why does it matter for online gaming?

NAT (Network Address Translation) controls how your router connects your console to the internet. NAT Type 1 is Open — best for gaming, connected directly to the internet. NAT Type 2 is Moderate — normal home setup, works well for most games. NAT Type 3 is Strict — your router is blocking connections, which prevents many online features from working.

Will a VPN fix this error?

A VPN is unlikely to fix CE-117519-4 and may make things worse. VPNs add latency and can interfere with the ports PlayStation uses for online connections. Fix your NAT type or check PSN server status instead — those address the actual cause.

This only happens in one game — is the problem on my end or the game's servers?

If the error only occurs in one specific game, the problem is likely with that game's servers rather than your PS5 or internet connection. Check the game publisher's social media or server status page for outage reports. Try again later — game servers can have brief outages during updates or peak hours.
