Users unable to join a zoom meeting

Hello

I was hosting a zoom meeting and there were some users who could join with the zoom link immediately, and others were being asked for a meeting password after the zoom link was clicked. When they entered the meeting password they were denied access.

I am unsure if the issue comes from me creating zoom links months in advance, but I have had issues with zoom links intermittently. I created a new link and sent it out which resolved the issue. Has anyone had a similar issue?
