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/dd5579e0eb07202988a0800619e5df922c356f10/MediaBrowser.MediaEncoding/Subtitles/ISubtitleWriter.cs
You should set ROOT_URL correctly, otherwise the web may not work correctly.
