I can't believe, I am still seeing the error that site can't be reached.

You have a problem that is local to your browser, your workstation, or the network you are on. You can be in disbelief all you want, but the fact remains that your site is working fine.

I can confirm what @EEAA is saying. Works fine here.

Check your computer's hosts file. Maybe you pointed the IP somewhere else for development?

@ceejayoz how can I do that? Also I called godaddy support. That guy also verified that he is seeing could not resolve dns error.

@RachitGupta Why are you involving GoDaddy? They have nothing to do with this?

@RachitGupta GoDaddy's tech support folks are, in my experience, entirely incompetent. Their main goal is to get you to go away. whatsmydns.net/#A/techsteroid.com shows DNS servers all over the world correctly resolving your DNS records. I do see the links on the site going to the EC2 hostname - you likely need to change your WordPress URL per the instructions at codex.wordpress.org/Changing_The_Site_URL.

yes, but the point is that if you two can see the the site, why can't he??

You should read more about DNS here: en.m.wikipedia.org/wiki/Domain_Name_System

can you also tell me whether to use public or private hosted zone and while entering domain name, I should prefix www or not?

Your DNS setup is fine. Do not change it. The issues you are seeing are local to your workstation or laptop. I don't know how to make myself any more clear.

But the reality is that I am unable to login to WordPress and start blogging and writing posts. If you can, then pls suggest what can be done.

You need to examine your local system. There is nothing wrong on your server, nor in your DNS setup. There is nothing further we can help you with.

I guess I know what is happening with your site.When you go to this Link techsteroid.com/wp-admin what are you getting?

@error2007s I am seeing unable to reach this site. DNS could not be resolved. Both on my laptop and mobile. however I can reach the site by accessing public dns of the ec2 instance

Is your host file set or some thing? I able to reach your site can you try some different computer?

@error2007s everyone is able to reach my site. Only me and devices on same network are not. A friend who lives nearby and has connection of the same company is also not able to reach.

DO you use MAC or Windows?

@error2007s Windows
