IIS: Accidentally deleted IIS Binding Port 80

After added HTTPS port for IIS Website, usually I’ll remove default port 80. 

Sometime i did regret that deleted it. Reason is when add back the port 80, can’t proceed to enter OK with empty hostname.

Spend some time to google but no luck. Go back to the create new Port 80 and enter hostname with URL name. 

Still that not resolve the issue yet. No issue to access the portal from URL name. 
But by hostname and localhost not going to work. 
Go back to Binding setting and try to remove the Host name entered earlier.
Wow ! I’m able to remove the host name and click OK now. 
Keep the post for myself and it could save your time too.
