WV-40303-5
Sony PlayStation
Severity: MinorWhat Does This Error Mean?
WV-40303-5 means a streaming video app on your PS4 ran into a connection or playback error. This is usually caused by a weak internet connection or a temporary problem with the streaming service's servers. Restarting the app and checking your connection speed usually resolves it.
Affected Models
- PlayStation 4
- PlayStation 4 Slim
- PlayStation 4 Pro
Common Causes
- Your internet connection is too slow or unstable for video streaming
- The streaming service (Netflix, YouTube, etc.) is experiencing a server outage
- The app's cached data on the PS4 has become corrupted
- Your PSN sign-in session expired while the app was running
- The router dropped the connection briefly during playback
How to Fix It
-
Close the streaming app fully and reopen it. Press the PlayStation button, highlight the app icon, press Options, and select 'Close Application'. Wait 10 seconds, then relaunch it.
A fresh app launch clears any in-memory errors and re-establishes the connection to the streaming service.
-
Check if the streaming service itself is down. On your phone, open the same app or visit the service's website. If video does not play there either, the service is having an outage — just wait.
Netflix, YouTube, and other services have occasional outages that affect all devices, not just PS4.
-
Test your internet connection speed on the PS4. Go to Settings > Network > Test Internet Connection. For smooth HD streaming you need at least 5 Mbps download, and 25 Mbps for 4K. If your speed is lower, streaming will be unreliable.
Speeds drop when many devices share the connection. Try streaming at a quieter time, or disconnect other devices.
-
Delete and reinstall the streaming app. Go to Settings > Storage > System Storage > Applications, find the app, press Options, and select Delete. Then reinstall it from the PlayStation Store. This clears any corrupted app data.
Reinstalling does not affect your account login or streaming service subscription.
-
Switch to a wired ethernet connection if you are using Wi-Fi. Streaming video needs a consistent, low-latency connection. Plug an ethernet cable from your router directly into the PS4 for the best streaming experience.
Wi-Fi signal interference from walls, microwaves, and other devices often causes intermittent streaming errors.
When to Call a Professional
WV-40303-5 is a software and network issue — no hardware repair is needed. If your internet speed is consistently too slow for video streaming on all devices, contact your internet provider. For speeds below 5 Mbps, HD streaming will be unreliable regardless of what you try.
Frequently Asked Questions
Why does streaming work fine on my TV but not my PS4?
Your smart TV and PS4 may be getting different connection quality. If the TV is wired and the PS4 is on Wi-Fi, that explains the difference. Also, smart TV apps are often more optimized than their PS4 counterparts — try using the TV app if PS4 streaming keeps failing.
Does this error affect my streaming subscription?
No. WV-40303-5 is a connection error and does not cancel or affect your subscription in any way. Your account, payment details, and subscription status are managed by the streaming service, not your PS4.
Can I stream in 4K on PS4?
The PS4 Pro supports 4K streaming on apps like Netflix and YouTube, but requires a 4K TV and a fast internet connection of at least 25 Mbps. The standard PS4 and PS4 Slim do not support 4K video output — they are limited to 1080p.
