Although the link you are trying to send might not really pose any security threat to you and your contact. Seems the system thinks it might be a threat therefore it is blocked. We value the messenger experience of our customers like you. We assure you that we will be looking into this concern. I will be forwarding this issue to our Subject Matter Experts so that it can be investigated and proper actions can be done.
Hopefully its resolved soon then.
