Venthyr maw assault issue/bug

anyone having an issue where it showed them 2/4 completed and they get D/C to come back to 1/4 complete while having 2 quests already turned in? Now that I have completed all 4 quests it’s showing 3/4 completed with no way for me to finish the assault.

I’ve seen some other reports of this. Try this and see if it helps:
