App connection problem on Mac

Hey there, 

I have a problem with the zoom ap connection on my MacBook. Although I can connect to my meetings using the safari browser, my zoom application cannot connect to the internet. I cannot sign in or join a meeting. I checked it with the university internet as well and the problem hasn't been solved yet. I also restarted my Mac and uninstall and install the app according to some solutions on websites but it didn't work as well. My OS and app are both updated. I made all the permissions that were needed for the zoom app as well. 

It is really strange because I previously worked with the zoom app on my Mac. 

Can you help me with that?
