I'm hosting several websites at home behind Nginx Reverse Proxy that handles HTTPS and certificates.
My problem is on some of them I can see a secondary certificate being called. For exemple if I go test my website domain.xyz on SSL Labs it shows a secondary website for anotherdomain.xyz.
I know there has to be something I did wrong and I be happy to learn how to improve.
Thanks for any answers you can give
