I am currently trying to complete the MSQ “The Oracle of Loght”. After completing the fight and watching the following cutscene, the system appears to be loading into the new zone but I keep getting the error message “An unexpected error has occurred. Exiting Final Fantasy XIV. (17)”

When I log back in, it takes me right back to the final cutscene where I get the same message at the end of it. I can world hop to and from my home world and complete dungeons and other events.i just can’t get past this quest to get to the next zone to continue the story. Please help.
