Thank you all for your quick responses and time that you put in. But as I suspected, it must be just a DNS propagation issue I guess.
I am now able to access my sub-domain as well: testing.moviechalo.com

I am not sure what a dedicated IP address is! But yes, this is the only IP address I see in my cPanel account information section. So, I guess, this must be the address!

I checked in my cPanel, I also have this A record.

*.moviechalo.com. 14400 IN A 192.254.233.216

And the link you provided, I had checked it before and as mentioned for cPanel, I created one subdomain as *.moviechalo.com and it is pointing to the right location.
My other DNS entries have the name ‘moviechalo.com’, only this record is using the IP address, the rest are using the domain name. Can it be an issue?

And I am wondering, if this was the case, why did it work perfectly the last night?

Or can it be a just a DNS propagating issue? But still the same question, how come did it work earlier!

Please post links to your domain and a subdomain.

Main site link: moviechalo.com

currently you will see a maintenance page, as I have activated wp-maintenance plugin for that

Sub-domain link: testing.moviechalo.com

I have previously worked with subdomains and multisite, this is first time it happened.

In your wp-config.php file,you must also have this line:

define( 'WP_ALLOW_MULTISITE', true );

Just add this line also. I guess it should work.
