I've been trying for over an hour to connect to Zoom meetings through my Mac's Zoom app. I cannot even log in, it states there is no connection. However, my friend is able to start, login, and connect to meetings on the same wifi. I don't have a VPN, I've disabled the firewall, I've restarted my computer and the app, I've re-downloaded the app, I've done absolutely everything. Zoom's live customer service isn't allowed to me, and I'm panicking because today is the first day of the semester. Please help.
