ZOOM does not work

I have had ZOOM for a long time, I am a web developer and I connect with fiber optics at 400mb browsing speed (all the time). Still, when I was in a meeting on ZOOM everything was cut off and I never had access again. I've tried deleting, uninstalling and reinstalling, clearing cookies and still can't access the Zoom platform properly. I repeat that I have an internet connection and still the response from the platform is the same: "Cannot connect to zoom. Check your network connection." So what do I do to get back to normal?
