You must give the Live IP address on Alternate access mapping for the particular SharePoint site. If we didn't map the IPAddress to Alternate access mapping, you can face similar issues on accessing the site, list and other objects from the Site. And also you can't view the List's View pages and settings pages for that site.
And also you can't access the site using SharePoint Designer.
