Can't get into deadmines to finish off quest

I have been trying for 2 days to finish off A vision of past to get out of Westfall with my level 120 rogue and for some reason, it will not let me into the deadlines so I can finish it. I can get into deadmines with my other high levels why not this one?

NVM, I just saw the message when I was in deadlines saying boosted characters can no longer enter legacy dungeons or raids try again tomorrow. Funny thing is i have been trying for 2 days lol.
