Sony PlayStation 5 CE-33991-5 Fix: No-Nonsense Network Guide

What This Error Means

CE-33991-5 means connection to the server failed or timed out.

The PS5 can see your network, but the link out to PlayStation Network (PSN) or the game server keeps dropping or never completes.

Official Fix

Here is Sony’s official playbook, translated into normal language:

  • Check if PSN is down or under maintenance. If it is, you wait. Nothing you do locally will fix it until Sony brings it back.
  • On your PS5 go to Settings > Network > Connection Status > Test Internet Connection. If this fails, the problem is before PSN (router, modem, or ISP).
  • Power-cycle the whole chain: fully shut down the PS5, unplug it, then unplug router and modem for 60 seconds. Plug modem back in, wait for lights to stabilize, then router, then PS5.
  • If you are on Wi‑Fi, move the console closer to the router or clear big metal/brick obstacles between them. Re-run the network test.
  • Try a wired link: run an Ethernet cable from router directly to the PS5 and test again. This rules out flaky Wi‑Fi.
  • Update system software: Settings > System > System Software > System Software Update and Settings > Update System Software > Update Using Internet.
  • Close and reopen the game or app that threw the error. If it is still the only title failing, delete and reinstall that game.
  • If everything else online works but PSN sign-in fails, confirm your PSN ID and password, and make sure the account is not suspended or restricted.

If all that passes and CE-33991-5 still appears, Sony says to contact your ISP or PlayStation Support.

The Technician’s Trick

What the field techs actually do when the official steps do not kill this error:

  • Bypass the router. If you have a separate modem and router, plug the PS5 by Ethernet straight into the modem and run the internet test. If it works now, your router is the bottleneck.
  • Manual DNS. On PS5: Settings > Network > Settings > Set Up Internet Connection > pick your connection > Advanced Settings. Set DNS Settings to Manual and use Primary 8.8.8.8 and Secondary 1.1.1.1. Test again. Bad ISP DNS triggers this a lot.
  • Force a clean IP lease. In Advanced Settings, set IP Address Settings to Manual. Give the PS5 an unused IP in your router range (for example 192.168.1.50), keep subnet mask and default gateway matching your router, and DNS as above. This dodges flaky DHCP on cheap routers.
  • Test with a phone hotspot. Turn on hotspot on your phone, connect PS5 to that Wi‑Fi, and run the test. If CE-33991-5 disappears, your console is fine; the issue lives with your home router or ISP. Just watch your mobile data.
  • Kill “smart” filters. Log into the router and temporarily disable parental controls, web filters, ad-blocking, heavy QoS rules, and any branded “gaming accelerator” or “security suite” features. These often block or throttle PSN traffic.
  • Fix double NAT. If you are running an ISP box plus your own router, put one into bridge mode or DMZ it so you only have one layer of NAT. Double NAT is a classic cause of random PSN disconnects and CE-33991-5.
  • Give the PS5 a cleaner path. Replace weak Wi‑Fi with something solid: long Cat6 cable, powerline adapter, or a closer access point. The fewer hops and extenders, the better.

If CE-33991-5 survives all of that, you are likely looking at a failing router, an ISP routing problem, or in rare cases a bad network chip on the PS5 itself.

Is It Worth Fixing? (The Financial Verdict)

  • ✅ Fix: When other devices also have random dropouts, or the PS5 only fails on this connection. This is almost always a network or router problem and cheap to fix compared with a new console.
  • ⚠️ Debatable: When you would need to pay someone to redesign or rewire a messy home network just for smoother PS5 online play. Think about how much you actually use online features before throwing money at it.
  • ❌ Replace: When a reputable shop confirms the PS5 LAN or Wi‑Fi hardware is dying, it is out of warranty, and the mainboard repair quote lands close to the price of a replacement console.
