Your ROOT_URL in app.ini is https://git.cloudchain.link/ but you are visiting https://dash.bss.nz/open-source-mirrors/jellyfin/blame/commit/898bb955641e9ddfe5347d4406960f363b100eac/Jellyfin.Api/Models/SyncPlayDtos/SetPlaylistItemRequestDto.cs
You should set ROOT_URL correctly, otherwise the web may not work correctly.
