I recently used letsencrypt for the first time and thought I&#x27;d have a certificate for each of multiple subdomains, where subdomains include e.g. dev. and staging.<p>Just about to launch a new website, googled the main domain to see if it&#x27;d been indexed, and discovered, to my horror, that each subdomain is shown as a result on a certificate details website, with the subdomain as the page title.<p>The subdomains are all 403 with an IP whitelist, with some basic authentication on top, but even having these subs listed exposes more info than I&#x27;d like.<p>Has anyone else experienced this? Could this be a feature peculiar to letsencrypt?<p>Any tips on preventing this happening again without resorting to wildcard certificates or dedicated development domains, and perhaps on removing references to subdomains from search engines?<p>Thanks
