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/c147b64de86f2245ff11087f21738a290f876065/MediaBrowser.Controller/Plugins/IPluginConfigurationPage.cs
You should set ROOT_URL correctly, otherwise the web may not work correctly.
