Failed to get AAAA from MX or your DOMAIN

[wkey]

So, I am trying to do the certification for rDNS bit, and when I try to run the check it pops up with: Failed to get AAAA from MX or your DOMAIN. I know this issue has popped up around a few times, but it looks like i have it setup correctly. I set the server for nslookup to the HE caching server, and also when using the dig command, but it still pops up with this error. Please advise!

nslookup

> set q=mx
> audiacloud.com
Server:         74.82.42.42
Address:        74.82.42.42#53

The caching name server you queried isn't the one the server uses. Either wait for negative cache to expire (you have a ttl of 86400 used, so it gets cached for that long), or email ipv6@he.net asking to flush cache.

Awesome!! Thanks! Yeah, I have waited for 2 days; is that normal?

Rarely happens, but sometimes it would get wedged enough needing a SIGKILL and then a clean start.

If they ran rndc flush on their side, would it accomplish the same thing?

Thanks for the suggestion!!  ;D
