Subtitles failing to retrieve

[Masch571]

I'm experiencing issues retrieving subtitles on my media website when using Jellyfin as the backend. While subtitles work perfectly in the Jellyfin web interface, they do not load on my custom frontend.
Specific details:

• The media item has subtitles confirmed in Jellyfin (HasSubtitles: true)
  
• External subtitle file exists: AllamericanS1E1.eng.srt
  
• Subtitle Extract plugin has been installed
  
• Attempted multiple subtitle loading methods without success
  

I've verified:

• Subtitle file is in the correct directory
  
• File permissions are correct
  
• Jellyfin server is configured to allow subtitle access
