Can I fully remove or disable my onhercules.app subdomain after connecting a custom domain?
Can I fully remove or disable my onhercules.app subdomain after connecting a custom domain?
No. The onhercules.app subdomain is permanent and cannot be removed or disabled. Every Hercules
app keeps its onhercules.app address.Do not add robots.txt blocking or a noindex tag in your app. The same app serves both hostnames,
so that would deindex your custom domain too. To prefer your custom domain in search results,
ask Hercules to set canonical URLs to that domain. See Branding & SEO.
