Answer 1

not sure if your still looking into this, or if it will work for you, but i had a similar setup and had the same issue. I eventually found i was urlencoding one to many times. Try commenting out this section:

 $keys = $this->_urlencode_rfc3986(array_keys($params));
        $values = $this->_urlencode_rfc3986(array_values($params));
        $params = array_combine($keys, $values);

Worked for me, so maybe it will help.
