Meetings wont connect

I have restarted and updated,  my laptop, I have uninstalled and reinstalled zoom, and done everything I can that has been written about to get zoom to work on my laptop. I cannot get a connection to any meetings. It works perfectly fine on my phone. As a student, I NEED zoom to work. I'm not sure what else to do here. It also won't let me update the zoom app. It just says check version failed.
