Downloading subtitle doesnt work with jellyfin 10.11.7

[saiwal]

Downloading subtitles shows the following error message:

jellyfin  |    at Jellyfin.Api.Controllers.SubtitleController.DownloadRemoteSubtitles(Guid itemId, String subtitleId)
jellyfin  | [18:25:59] [ERR] [19] Jellyfin.Api.Controllers.SubtitleController: Error downloading subtitles
jellyfin  | System.ArgumentException: Invalid subtitle format: srt

Search works. srt file works if downloaded via browser and added manually to media.

[MBR-0001]

Should be fixed with jellyfin/jellyfin#16539
