Hi,

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 [https://letsencrypt.org/docs/rate-limits/](https://letsencrypt.org/docs/rate-limits/)”.

I created two DNS type A (squadnps.adttemp.com.br and www.squadnps.adttemp.com.br) but happens same error “DNS problem: NXDOMAIN looking up A for”

Att.

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

Your two domains have ipv4 - addresses ( [https://check-your-website.server-daten.de/?q=squadnps.adttemp.com.br](https://check-your-website.server-daten.de/?q=squadnps.adttemp.com.br) ):

| Host | T | IP-Address | is auth. | ∑ Queries | ∑ Timeout |
| --- | --- | --- | --- | --- | --- |
| squadnps.adttemp.com.br | A | 191.232.166.88 | yes | 1 | 0 |
| | AAAA | | yes | | |
| www.squadnps.adttemp.com.br | A | 191.232.166.88 | 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 - [https://unboundtest.com/m/A/www.squadnps.adttemp.com.br/HJWD2WSP](https://unboundtest.com/m/A/www.squadnps.adttemp.com.br/HJWD2WSP)

Share your complete command.

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