Some DNS records were found that indicate TXT records may have been incorrectly manually entered into DNS editor interfaces. The correct way to enter these records is to either remove the domain from the label (so enter "_acme-challenge.www.example.org" as "_acme-challenge.www") or include a period (.) at the end of the label (enter "_acme-challenge.example.org.").
The following probably-erroneous TXT records were found:
_acme-challenge.double.monkas.xyz.double.monkas.xyz. 0 IN TXT "XXX"
_acme-challenge.double.monkas.xyz.monkas.xyz. 0 IN TXT "XXX"
Challenge update failures for double.monkas.xyz in order https://acme-staging-v02.api.letsencrypt.org/acme/order/5751349/174808486
acme: error code 403 "urn:ietf:params:acme:error:unauthorized": No TXT record found at _acme-challenge.double.monkas.xyz
