Letsencrypt No valid IP found

Hi all,
I’m having issue getting certificate for my domain , here’s the error:

Failed authorization procedure. test.dzonerzy.net (http-01): urn:acme:error:unknownHost :: The 
server could not resolve a domain name :: No valid IP addresses found for test.dzonerzy.net

IMPORTANT NOTES:
- The following errors were reported by the server:

Domain: test.dzonerzy.net
Type:   unknownHost
Detail: No valid IP addresses found for test.dzonerzy.net

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address.

Anyway my DNS seems well configured, here’s the A record

dzonerzy-5:~ dzonerzy$ dig test.dzonerzy.net

Any suggestion?

Your nameservers do not implement 0x20 mixed case.

$ dig @ns1.rbind.us tESt.dzonerzy.net
