Wyrmrest Accord Quest Chain

Hello!
I hit level 80 a few days ago and of course I abandoned all the quests I already had. Today I wanted to do the quest chain to farm reputation with Wyrmrest Accord in Dragonblight. I am stuck at quest "Prevent the Accord" (https://www.wowhead.com/quest=12004/prevent-the-accord) and by stuck I mean the NPC doesn't have any quest to give me and as far as I remember I did the quests before this one. I need to have this quest in order to continue my chain. Is there any way to get some help please? I would be very grateful!
