### Region

China

### Example URLs

### Provide a description that is worded well enough to be understood

Currently, the extractor requires a proxy to bypass geo-restriction. Despite that `X-Forwarded-For` does not work and the extractor therefore has `_GEO_BYPASS = False`, the restriction can be bypassed using a `X-Real-IP: 118.88.88.88` header in the API request, without need for an actual proxy.

```diff
 def _call_player_api(self, song_id, level): 
     return self._download_eapi_json( 
         '/song/enhance/player/url/v1', song_id, 
         {'ids': f'[{song_id}]', 'level': level, 'encodeType': 'flac'}, 
+        headers={'X-Real-IP': '118.88.88.88'},
         note=f'Downloading song URL info: level {level}') 
```


### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below

You might want to use a VPN or a proxy server (with --proxy) to workaround.
