Stuck and can't progress

I’m stuck on a part after the boss. I killed the boss on Dreadnought’s Deck and I pressed the interact item to jump off the ship, but got DCed instead. Now there’s nothing there and I can’t progress the game.

I tried killing the boss 3 more times and there’s no way to progress the game. I have no quest either. My partner is in the same situation, we were playing together. Tried relogging, restarting, doing it solo, etc. Nothing worked.

What do I do?

Edit: I found a work around. A player invited me in party to where the next quest is supposed to be and I got it. But until then, I couldn’t progress in any way.
