DNS issue - server IP address could not be found

Question

My domain (ecokrypt.com) is with godaddy

Yesterday I tried making some changes, after that my DNS has stopped resolving to IP address. I get below error:

This site can’t be reached

 ecokrypt.com’s server IP address could not be found.


Search Google for ecokrypt
ERR_NAME_NOT_RESOLVED

My current setting is as per attached image.

1. Tried clearing my browser history

2. Power off my router box

3. I event tried changing it to route 53 name servers, but I always get above error.

4. If I use direct IP - I do see my website (partially as without DNS name it will give me error)

5. Tried pinging ecokrypt.com from my local machine, I get unknown host

I am just unable to understand what is wrong.

UPDATES# Tried dig command as suggested below and it seems ok. So looks like I have to wait till upstream cache gets cleared.

You probably need to clear your DNS cache. DNS results (including not found results) can persist in cache for some time. What's worse, is that those results can be cached by upstream DNS servers, so even if you clear your local cache it might take anywhere from an hour to a day for the changes to propagate across the network.

A good way to test your DNS config is to force resolution using a well-behaved DNS server.

If you're using dig on a *nix box, it'd be something like:

dig @8.8.8.8 foo.com

8.8.8.8 is the google DNS resolution service.

You can also use your resolution service directly:

dig @ns67.domaincontrol.com foo.com
