Accepted Answer

For anyone in need:

You can return a response message from the server using echo. Then in the js code add an error event handler

PHP

```
header("HTTP/1.0 400 Bad Request");
echo "Ups error message";
```

JS

```
this.on('error', function(file, response) {
    $(file.previewElement).find('.dz-error-message').text(response);
});
```
