PlayStation Error Code NP-104363-0 — What It Means & How to Fix It

What Does This Error Mean?

NP-104363-0 means your PS5 cannot connect to PlayStation Network servers. The connection request timed out or was refused. This is usually a temporary issue with PSN or your internet connection.

Affected Models

PlayStation 5

Common Causes

PSN servers are under maintenance or experiencing an outage
Your home internet connection is unstable or too slow
Router firewall is blocking PlayStation network traffic
DNS server is failing to resolve PlayStation addresses
NAT type is too strict and blocking the connection

How to Fix It

Check if PSN is currently down.

Visit status.playstation.com on your phone or computer. If PSN shows any issues, wait and retry later.
Restart your router and console.

Unplug your router for 60 seconds. Turn off your PS5 fully. Then power everything back on and try again.
Test your internet connection on the console.

Go to Settings > Network > Test Internet Connection. Note the NAT Type — it should say Type 1 or Type 2.
Switch from Wi-Fi to a wired ethernet connection.

Plug an ethernet cable directly from your router into the PS5. Wired connections are much more stable for PSN.
Change your DNS to Google DNS (8.8.8.8).

Go to Settings > Network > Set Up Internet Connection. Use Custom and enter 8.8.8.8 for primary and 8.8.4.4 for secondary DNS.

When to Call a Professional

If you have tried all fixes and still see this error, contact your internet provider. They can check if any ports required by PlayStation are being blocked on their end.

Frequently Asked Questions

What is NAT Type and why does it matter?

NAT Type tells you how open your connection is to other players and servers. Type 1 is fully open. Type 2 is moderate — fine for most things. Type 3 is strict and can cause connection errors like this one.

Could my ISP be blocking PlayStation?

It is rare but possible — some ISPs block certain ports that PlayStation uses. Try connecting through a mobile hotspot and see if the error goes away. If it does, contact your ISP about opening the required ports.

Does this error delete any of my games or data?

No — this is a network connection error only. Your games, saves, and account data are all safe. Fixing the connection will let you access everything normally.
