Too many requests


I would like some help about this problem, it tried a lot of times because this error “DNS problem: NXDOMAIN looking up A for” and then blocked because too many requests: “An unexpected error occurred: There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see”.

I created two DNS type A ( and but happens same error “DNS problem: NXDOMAIN looking up A for”


Hi @cmenezes

are you sure you don't have a typo in your command?

Your two domains have ipv4 - addresses ( ):

Host T IP-Address is auth. ∑ Queries ∑ Timeout A yes 1 0
AAAA yes A yes 1 0
AAAA yes

There is no DNSSEC-problem visible.

And rechecked both domains via Unboundtest (nearly the same configuration Letsencrypt uses) there is no error -

Share your complete command.

"Too many failed" isn't a big problem, only one hour.
