How to resolve this issue?

The message says it all.

too many new orders recently: see https://letsencrypt.org/docs/rate-limits/"

Also look under the Rate Limit section of this document:
https://www.directadmin.com/features.php?id=1828

So the solution is not to run all ssl requests at once, but doing them according to the rate limits mentioned and you should be fine.
