Meetings show Registration closed to students when it's not

[Susan222]

Just last week, my students haven't been able to get into my weekly meeting. Each student registers for their own log in link and for years all has worked fine. Now, almost all of them are unable to get in because it says Registration Closed. But, I've not closed registration and can't figure out how to open it. And, the oddest thing is that one student could get on today but everyone else couldn't. I've updated my zoom  to the latest and it is still happening. I use Chrome on a mac. Please help.
