that domain authed in dns service and I can create cert for only origin 5 dns.
all dns hosted on same server.

hope your kindly helps.
You must use HTTPS:// and it should work fine (see below).
You chose to use --standalone which uses port 80 (HTTP) for the cert challenge. If you want HTTP to work for your web server you need to review your configuration.
