Daily Trivia in Caverns of Time

Several of my characters, all between level 111 and level 113, have been unable to pick up the daily trivia question from Historian Ju’pa. The funny thing is, 2 of my other characters on the same server that are level 113 are able to do the daily trivia question.

None of my characters are experience locked. They have turned in the quest item from the anniversary celebration package, and were able to pick up and turn in the daily trivia question up until a few days ago. However, since two days ago, they are unable to do so.

Any ideas? Thanks in advance!

EDIT: After checking 5 characters on a different server, none of them are able to pick up the daily trivia quest. They range from level 85 to level 112. They did the trivia question a few days ago, and I finally got around to doing it again today (11/16/19).
