Your ROOT_URL in app.ini is https://git.cloudchain.link/ but you are visiting https://dash.bss.nz/open-source-mirrors/Sonarr/src/commit/1218dd255faf52bcd984a775193c8330bb8c1f04/osx/Sonarr.app/Contents/Resources/sonarr.icns
You should set ROOT_URL correctly, otherwise the web may not work correctly.
