I've never had anything like this with my dragon. He was very friendly since childhood, never hissed or bitten. I've never even seen a
black beard. But it seemed to me that we were brought even closer together by the fact that I let him fall asleep on my chest in the evening, I cover him with a fleece baby blanket so that the light does not disturb him. After this, Foxy began to perceive me as a "safe place", and very often asks to just sit on my shoulder or chest. Perhaps this will help someone strengthen their connection with their dragon.
