-##   ssl.pemfile = "/path/to/server.pem"

+##   ssl.pemfile = "/path/to/fullchain.pem"
+##   # ssl.pemfile should contain the sorted certificate chain, including
+##   # intermediate certificates, as provided by the certificate issuer.
+##   # If both privkey and cert are in same file, specify only ssl.pemfile.
