[Solved] IIS site is not working outside windows server with custom domain name

Hi Team,

With the help of below link i have configured IIS website. 

https://www.c-sharpcorner.com/article/how-to-change-localhost-to-custom-domain-name-in-iis/

But the site with custom domain name www.mysite.com only works inside the windows IIS server. ON difference same n/w machines it’s not working.

Getting some errors like DNS related.

Please help on this.
