Hi,
I just checked it and your site is returning this message:
This site requires Javascript to work, please enable Javascript in your browser or use a browser with Javascript support.
when the app tries to connect to http://sandeshjain.com/moodle/login/token.php.
It also includes a couple of Javascript scripts. That shouldn't be done in that request, the app expects to receive a JSON response, not some HTML content, that's why it fails.
Kind regards,
Dani
