As stated before your description is quite hard to understand.

However I do see something in your code that in your code that makes me think that your looking for the error handler of the ajax object.

 

In your code I see this :

var warning = "<font color=\"red\">Unable to load server details</font>";

 

To see if an error occurs try something like:

$.ajax({
    success: function() {
        // your normal action when the server call is running as expected
    },
    error: function() {
        // your code when a error occurs on the server such as a timeout
    }
});

 

if this was not what you were looking for can you try again describing your exact problem?
