We have one user , when he is trying to access the server by using the hostname it is not getting connected but when user is able to access with the IP address . and did work around by configuring the host entry on the user name .
So we have checked on our admin portal and could see that hostname is configured on our app. segment with disabled DNS port means we have alowed only 8080 and 443 ports .
Can someone explain why it is not working with the hostname?
is there any thing needs to be done from my end to fix this DNS issue .
