Nginx is configured to use TLS but no certificates are created:
nginx: [emerg] BIO_new_file("/etc/pki/tls/certs/localhost.cert.pem") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/pki/tls/certs/localhost.cert.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
There is no documentation of creating certificates in the "Full installation" manual.
