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/7578dfac25316946d7a65123573d404d8965937d/MediaBrowser.MediaEncoding/Subtitles/JsonWriter.cs
You should set ROOT_URL correctly, otherwise the web may not work correctly.
