I'm trying to enable SSL on my current Nginx configuration, which works fine. However I'm wondering if it's possible to do this alongside HTTP, so that i do not need another server{} section which would just be a replication of the http section. I thought the following would work, however i get the below when accessing http:// 400 Bad Request The plain HTTP request was sent to HTTPS port Nginx Config: ssl_certificate /etc/nginx/ssl/domains.pem; ssl_certificate_key /etc/nginx/ssl/server.key; server { listen 80; listen 443; //other configuration }
