Creation of new certificate failed due to domain validation

1

When I am trying to create a new certification I am getting this error:

Validation of the required challenges did not complete successfully. Domain validation failed: ragentbeta.multiarray.com
20.53.139.220: Invalid response from http://ragentbeta.multiarray.com/.well-known/acme-challenge/45xEoNXw_pvmVmgK6DEjTdAeuIiBRDc_eHovsnkmc1o: 404 Forbidden urn:ietf:params:acme:error:unauthorized

Hi, your domain seems to resolve to two different IP addresses:

ragentbeta.multiarray.com. 0 IN A 20.53.104.47
ragentbeta.multiarray.com. 0 IN A 20.53.139.220

If these are not both the same server then http validation (the default domain validation) will not work because they won’t both return the same result for the http challenge process.

If you are intentionally load balancing the domain you should use DNS validation instead. See also DNS Validation (dns-01) | Certify The Web Docs
