Renown stuck at 16

I leveled an alt and got my renown to 16 but now its stuck there. I did all the covenant quests I could possibly do, farming all LFR’s, dungeons, torghast, winning multiple BG’s but no drop. All I need is 1 more renown to continue to the next quest line…

I have the same problem for almost a week. Everything I do nothing increase my renown. Been doing the same things and nothing.
