Unable to verify DNS

[longshum7]

I am unable to verify my domain. It keeps returning

ERROR com.jblur.acme_client.command.certificate.VerifyDomainsCommand:100 - Domain SG-awsRedisTSL-17.devservers.scalegrid.io is not verified. Please, check warnings.

I have verified that the TXT record exists in _acme-challenge.SG-awsRedisTSL-17.devservers.scalegrid.io and the digest value matches.

I am running java 1.8
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Any idea what went wrong?

DNS record not found:

Make sure you TXT record / records exist

Also, if you failed challenges you may potentially need to recreate challenges again (just remove files in your workdir and re-register challenges again)
