I have a SharePoint internal site that I'd like to load into a custom URL placeholder. However when I do so, the placeholder remains blank.
Let's say the URL I'm trying to load is http://cetwebapp/webapp/SitePages/Page1.aspx.
It doesn't load - placeholder is blank in the preview and on the display. If I change the server name to the actual server name (http://SPserver/webapp/SitePages/Page1.aspx), my server produces an error page, Page not found, as expected, since the /webapp/ doesn't exist on SPserver, it exists on cetwebapp. That error page however loads into the custom URL placeholder.
If I use a "proper" URL, such as http://cetwebapp.domain.com/webapp/SitePages/Page1.aspx, the URL placeholder remains blank.
Both the http://cetwebapp/webapp/SitePages/Page1.aspx and http://cetwebapp.domain.com/webapp/SitePages/Page1.aspx load fine in the Chrome app of the Chromebox.
Would you know what might cause the SharePoint site to not load?
