Test result for bright.aura-software.com using http-01

bright.aura-software.com has an AAAA (IPv6) record (2600:3c03::f03c:91ff:fedf:304f) but a test request to this address over port 80 did not succeed. Let's Encrypt will prefer to use AAAA records, if present, and will not fall back to IPv4 records. You should either ensure that validation requests to this domain succeed over IPv6, or remove its AAAA record.
