Yeah! I've found the solution!
There is a request code example:

$.ajax({
	url: 'https://food-tracker.ru/foods',
	type: 'POST',
	dataType: 'JSON',
	data: {term: 'rjk'},
	success: function (data) {console.log(data);}
});

And there was server code:

protected function returnJSON($data) {
    header('text/html; charset=utf-8');
    echo json_encode($data);
    die(0);
}

The solution is to change line header('text/html; charset=utf-8'); to header('Content-type: application/json; charset=utf-8');

So, right working code is:

protected function returnJSON($data) {
    header('Content-type: application/json; charset=utf-8');
    echo json_encode($data);
    die(0);
}

Thanks for your attention!

P.S. But one question i still have: why was it working fine before, and brokes when just hosting changed?

@gydrus The page seems to load fine here, does this cause any problem to access the site?

A search for 'Ajax net::ERR_SPDY_PROTOCOL_ERROR' returned several results, did you try to check some of them?
