Teams doesn t work anymore

Hello,

I use Teams on a Mac. It did work. But it doens t anymore. When u try to start a planned meeting a note pops up that says there has been a problem wait several minutes and try again. Then I have to click on 'ok'. This happens for several days now. What can i do?

I already tried to reinstall Teams. But that didn t solve this problem.

does anybody have an answer? That would be great.
