Database connection with ip instead of url...

I need to set up a connection with my database on the ip address temporarily as the url cannot be moved yet to the new host.  I've set it up like the screenshot below, but I get "An unidentified error has occurred".  I've done this before in the past.  I just can't remember the settings that I used.  And, for example the ip address looks something like this to connect to the temporary site:  http://00.00.000.000/~example

Thanks in advance!
