Why You’re Seeing Error CE-34878-0 in Rocket League
This error is not always caused by something wrong with your PlayStation or internet connection. In many cases, it happens because of server-side issues with Rocket League.
When Rocket League’s console servers are down or experiencing interruptions, PS4 systems struggle to connect, causing the application to crash.
On forums like the Rocket League subreddit, players often flood in to report mass outages — which confirms the issue isn’t just on your end. In fact, the official Rocket League Status page on X (formerly Twitter) sometimes posts updates about known issues, such as:
“We are investigating an issue causing some players on PS4 and PS4 Pro to crash when attempting to boot up Rocket League. Updates to follow when we identify a fix.”
So in short:
-
It’s not your fault.
-
The error is linked to Rocket League’s servers or updates.
Methods to Fix or Work Around the Error
Here are several ways you can troubleshoot error CE-34878-0 on PS4:
1. Adjust PS4 Display Settings (Supersampling & Resolution Fix) ✅
One method that has worked for many players is adjusting your PS4’s display settings. If your PS4 is running in a higher resolution or using supersampling, Rocket League may crash.
Here’s how you can fix it:
-
Go to Settings > Sound and Screen > Video Output Settings.
-
Under Resolution, change it to 1080p.
-
If Supersampling Mode is enabled, turn it off.
Many users reported that as soon as they lowered their resolution to 1080p, Rocket League started working again without crashing.
👉 Personally, what worked for me was simply changing the resolution to 1080p, and the error disappeared.
2. Disconnect Your PS4 From the Internet
One temporary workaround is to play Rocket League offline.
-
Go to your PS4 Network Settings and disconnect from Wi-Fi or LAN.
-
Relaunch Rocket League.
-
You may be able to play offline modes like training or split-screen while waiting for servers to come back online.
Several players have reported that this bypasses the crash temporarily.
3. Restart Your PS4 and Router
Sometimes the error may be related to temporary network conflicts.
-
Restart your PS4 console.
-
Power cycle your router by unplugging it for 30 seconds and plugging it back in.
-
Reconnect and try launching Rocket League again.
4. Try a Different Internet Connection
If the problem persists, switch to another connection:
-
Use your mobile hotspot to test if Rocket League loads.
-
Try a different Wi-Fi network if available.
This can sometimes help if the issue is related to your ISP’s routing.
5.Check Rocket League’s Server Status
Before you start troubleshooting, confirm whether the issue is on Rocket League’s end.
-
Visit the Rocket League Status page on X (Twitter).
-
Look for announcements about outages or PS4-specific crashes.
-
If servers are down, you’ll have to wait until they are restored.
6. Reinstall Rocket League (Last Resort)
If none of the above works and the error keeps appearing only on your console:
-
Backup your save data to PS Plus cloud storage.
-
Delete Rocket League from your PS4.
-
Reinstall it from the PlayStation Store.
This ensures corrupted files aren’t causing the error locally.
Key Takeaway
Error CE-34878-0 in Rocket League on PS4 is usually caused by server-side issues, not by your console or internet. While it’s frustrating, the problem often resolves itself once servers are fixed by the developers.
Meanwhile, you can:
-
Play offline modes,
-
Restart your PS4 and network,
-
Try alternative internet connections,
-
Adjust resolution to 1080p or disable supersampling, or
-
Reinstall Rocket League as a last resort.
The best thing to do is to follow Rocket League’s official status updates to stay informed about outages and fixes.
