Hi MercuryMan,

Try to ping the server IP ensure DNS is configured correctly.

Refer to the following article to configure SharePoint alternate access by IP address:

I have added a host entry under with IP address and xyz.com. when I try accessing it pop's up.

I have also added binding with ip address to web application but still it gives the above error. Actually it was working with IP address too but from last 3days it started giving "Bad Request - Invalid Hostname (400)" error.
