Apply to the same University after a rejection
I would suggest that it would be worth re-applying only if something substantial and important has changed. The change could be with you, or it could be with the university.
You say that the job description is not the same as previously. That is a change, but I can't say that it is a sufficient change. Presumably the place has pretty high standards and a lot of applications.
It could also be that the recent emphasis in online education has made you a better fit. Or a possible drop in the number of likely applicants for the new position relative to the previous announcement.
But the change could also be with you. Have you improved your CV since the previous application? Have you gotten an important new advocate to write letters for you?
Maybe both things have changed enough for you to be a better fit now. But if not, it is unlikely to be any more successful in this cycle.
