I had the exact same problem. Dont know if this is today only, as I didnt use matlab for a while.
I fixed it by activating a 2022a license for my 2020a version :face_with_raised_eyebrow:

Hi, we aren’t managing the flexlm license manager for Matlab, we are only using it. The server was probably down for a maintenance reason. Is the error solved?

Yes it was a widespread error in all Unige computers. It is solved now.
