Certificate name mismatch

Help

I executed this:
./certbot-auto certonly --manual --preferred-challenges dns-01 -d romicvawebtrees.duckdns.org -d romicva.duckdns.org

got a token TXT that I ran through duckdns and got OK

However it error-ed out like this:
Press Enter to Continue
Waiting for verification…
Challenge failed for domain romicva.duckdns.org
dns-01 challenge for romicva.duckdns.org
Cleaning up challenges
Some challenges have failed.
