CNAME not resolving

CNAME not resolving

I set up the MX records, and using a DNS checker I can see they are properly set. However, the CNAME record apparently does not exists. I have them set up with the domain registrar though, however, see this image:

I've waited 8+ hours already, and the CNAME still doesn't resolve, I get this error:



I've sent another email to the registrar, the first time they set the MX records to resolve properly and also set the TXT records (which I never asked them to do, and checking later I realized they didn't even add any TXT records so I have no idea why they said that). Hopefully the registrar can fix the issue, but I'm wondering if anyone else has had this problem, is there perhaps something wrong with my domain settings? I'm with Sibername.com.
