IIS Website – Can Ping Server IP but Can’t Reach by Domain Name

a-recorddomaindomain-name-systemiis

I have an A record pointing to my server via its' public IP.
It is set with the following host/value pair: @, 47.91.42.224
I can reach my server with this IP as it's the primary way I connect to it.
In my IIS site I have 2 bindings

  • mysomedomainname.com (not an actual name)
  • www.mysomedomainname.com (not an actual name)

both having IP address set to servers' private address. There are a total of 3 options for the IP dropdown

  • All unassigned
  • internal server address
  • some IPv6 address

I've tried using unassigned instead as well, but no luck. While I can ping the server, I can't reach my site via domain as it gives me a timeout. It's definitely not a content issue as there is a plain HTML document with 1 line of text. 

NSLOOKUP mysomedomainname.com

Executed from the server machinbe gives the following result:

NSLOOKUP : Non-authoritative answer:

Was an actual issue with port 80 as cloud provider had custom security groups configuration.
