Why did my Worker generate a new SSL certificate for my domain even though my domain already has a valid certificate? Can I delete the certificate that the Worker created?
Are you talking about Worker Custom Domains?
If so, they generate one as just part of their set up process. The default Universal SSL Cert only covers first level subdomains, like worker.yourwebsite.com but not worker.projects.yourwebsite.com. Custom Domains generate an Adv. Cert that lets you have your worker on a 2nd level or deeper subdomain.
You can navigate to SSL/TLS → Edge Certs of the domain and just delete the certificate manually if you want. Cloudflare explicitly states this is supported in the Worker Custom Domains Documentation. Once it’s deleted, it won’t come back.

Not needed, so I’ll delete it. The edge certificate covers it already. Thanks.
