Environment: SharePoint 2013 On premises
We are having SharePoint 2013 server with load balancing, and we have an DNS name for the load balancing. While we open the Central Administration page or SharePoint site with the DNS name (http://DNSname:portnumber/default.aspx), the page is not opening . But when we open with servername(http://servername:portnumber/default.aspx) it is opening.
Kindly suggest on how to get it resolve the problem.
