Error code WCP-UN-0 is a specific network connectivity error that primarily affects Crunchyroll users on Smart TVs (like Samsung, LG, and Sony) and set-top boxes (like Sky Q or Roku).
It essentially means the app is failing to establish a “handshake” with Crunchyroll’s servers, even if your TV says it’s connected to the internet.
How to Fix Crunchyroll Error WCP-UN-0
1. The “Power Cycle” (Most Successful Fix)
Don’t just turn the TV off with the remote—that usually just puts it in standby.
-
Unplug your TV from the wall outlet.
-
Wait at least 60 seconds (this clears the temporary memory/cache).
-
Plug it back in and try the app again.
2. Force Reinstall (Sky Q & Smart TVs)
If you are using a Sky Q box or a Samsung/LG TV, “refreshing” isn’t enough.
-
Delete the app entirely from your device.
-
Restart the device before downloading it again.
-
Re-download the Crunchyroll app from the store and log back in.
-
Note for Sky Q users: Some users have reported that a Factory Reset of the “Mini” boxes resolved this specific code when the main box wouldn’t.

3. DNS Adjustment
Sometimes your ISP’s default DNS settings struggle with Crunchyroll’s video delivery network. Switching to a more stable public DNS often bypasses the WCP-UN-0 error:
-
Go to your TV’s Network Settings > IP Settings > DNS Settings.
-
Change it from “Automatic” to Manual.
-
Enter 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
4. Check for “System Busy”
If you are seeing this error today, it could be due to a high-traffic release. On several occasions in February 2026, users reported this specific code during peak hours when servers were struggling to validate login sessions. If the steps above don’t work, wait 1–2 hours for server traffic to normalize.
