Can't register to Zoom meeting

Hello, I can't register to this meeting. Every time I click the link it displays "Unable to display this page. Zoom is temporarily unable to display this page."

The registration was working fine last time, don't know what happened. Tried it on FF, Chrome, and Safari but no luck. I disabled all addons and extensions, enabled all cookies, cleared the browser cache, nothing. It just immediately redirects to "https://us06web.zoom.us/error_display"

I'm not the meeting owner so I can't troubleshoot this from the admin side.

I've been at this for days now. Please help. Thanks!
