Your ROOT_URL in app.ini is https://git.cloudchain.link/ but you are visiting https://dash.bss.nz/open-source-mirrors/Sonarr/commits/commit/e71527565757802143c5dd0d4a558f2ab7b8c35f/osx-app/Sonarr.app/Contents/Resources/sonarr.icns
You should set ROOT_URL correctly, otherwise the web may not work correctly.
