A User-Agent is a string of text that Sonarr sends to websites to identify itself. By default, it identifies itself as Sonarr, which Cloudflare can easily block. Changing the User-Agent to mimic a common browser (like Chrome, Firefox, or Safari) makes Sonarr appear as a legitimate user, reducing the likelihood of being blocked. You can configure this in Sonarr's settings under 'HTTP'.
