An “OuterTune error code 403” indicates a “Forbidden” error, meaning the web server understood the request but is refusing to fulfill it. This typically occurs due to access restrictions rather than a server-side problem.
Here’s a breakdown of what “Error 403” (or “response code 403 / Playback Error 403 / Error Source (2004) / Forbidden”) in OuterTune likely means, and what you can try to fix it.
🔍 What Error 403 Means in OuterTune
It’s an HTTP status error meaning Forbidden — the app is not allowed to access the media resource.
In OuterTune’s GitHub issues, many users report that after ~10‑30 seconds of playback, the app throws 403 or 2004 (“Source error / response code 403”) and stops playing.
The root cause seems connected to changes in YouTube’s API or access permissions (since OuterTune uses YouTube as a source) and possibly restrictions on certain content (region, age, private/removed content, or account‑based restrictions).
⚠ Common Situations When It Happens
Song plays for some seconds, then errors out (often near 30 seconds)
Content is restricted (private YouTube video, removed video, not available in your region, or age restricted)
A required authentication or API credential either expired, changed, or revoked. OuterTune’s access to the content is rejected.

🛠️ What You Can Try to Fix It
Here are several actions to try; none guaranteed because some issues are on the content provider’s / YouTube’s side.
Fix | Steps | Why It Might Work |
|---|---|---|
| Update OuterTune | Go to wherever you install/update the app → check for updates → install latest version. | New releases may include fixes for API changes. |
| Log in / out | If OuterTune supports login (e.g. via YouTube or account), try logging out then in again. | Re‑authenticates permissions, refreshes tokens. |
| Use VPN (or disable VPN) | Try disabling any VPN or proxy first; if already off, try using VPN to see if region locking is the issue. | If resource is restricted in your country, VPN can help; or vice versa if VPN is causing conflict. |
| Try different content | Try playing a different song/video (not age‑restricted or private). | Helps test if it’s content‑specific. |
| Check YouTube / Content status | On YouTube separately, open the link (if you know it), check if video is private, removed, or age restricted. | If it doesn’t play on YouTube, OuterTune won’t either. |
| Clear app cache / reinstall | Go to device settings → Storage → clear cache/data for OuterTune; or uninstall + reinstall fresh. | Removes old/corrupted credentials, cache conflicts. |
| Check for OuterTune community updates | Look on GitHub issues (OuterTune repo) for posts about “403 / 2004” and see if there’s any patch/workaround. | Others may have found temporary fixes. |
🔎 When It’s Out of Your Control
If YouTube’s API has changed in a way that blocks OuterTune from accessing certain streaming data.
If the video/content is removed, private, or region‑locked by YouTube.
If the OuterTune app doesn’t have valid credentials (or they were revoked).
If the app is being blocked by YouTube’s Terms or policies, which leads to the 403 response.
