"Wrong Code" notification, even though the Code is correct!

[Clueless]

Hi,

I haven´t been able to access Zoom-Meetings on my Laptop for a couple of days now. Zoom gives me a notification, that the Access Code is incorrect. Meanwhile I can enter the meetings with the same codes on my IPhone. Using Zoom on my self-phone is not that convinient though, as I have to show some presentations. Please help!
