Asking questions is hard. The thing is, if we want to learn something important; we need to exchange it with something equally important.
There is the law of give and take. We can't expect people to share with us important information, if they don't trust us.
Equally important is to see us as someone who can understand the message.
That is why, don't ask yourself why you can't reach to the right people, but ask yourself what you need to do and invest in, to attract the right people to help you!
