Dana White's problem, or rather his source of conflict, seems to stem from personality clashes with certain fighters who aren't willing to simply go along and say yes to everything. Some big personalities in the world of MMA, like Tyron and Stipe, have had some beef with Dana apparently. These are fighters who've reached the top and aren't willing to just roll over. They are very aware of their power, position, and worth and aren't afraid to make it known. As for John Jones, his issues didn't seem to be about Dana specifically but more about his own actions outside the octagon. That's the thing about fighters though, they're strong-willed and independent, it's in their nature. When you mix that with the high stakes world of MMA, well things can get a little heated for sure.

Hey man, I'm not too sure about Dana White's specific health issues prior to participating in Gary Brekkas' program. The transcripts you've shown me here don't seem to mention anything about that. But as far as I know, Dana has always been a pretty hard-working guy, and that kind of high-stress life can definitely take a toll on your health. I would really need to dig into it more or even have a chat with Dana himself to get the real details.
