Your ROOT_URL in app.ini is https://git.cloudchain.link/ but you are visiting https://dash.bss.nz/open-source-guides/TRaSH-Guides/src/commit/178786827031d8879ddb361e4192608fcab2cf70/Sonarr/sonarr-setup-custom-formats-anime
You should set ROOT_URL correctly, otherwise the web may not work correctly.
