The Linux write-up on dealing with that is at https://www.mathworks.com/matlabcentral/answers/100235-why-can-t-i-activate-matlab-or-start-the-network-license-manager-in-a-newer-linux-environment and https://www.mathworks.com/matlabcentral/answers/102676-how-can-i-activate-matlab-on-a-linux-machine-that-does-not-have-an-eth0-device
However, those are not really relevant to Mac.
Do you happen to be using a MacBook Air or MacBook Pro that has no ethernet ports, just WiFi or a USB-C connector? Sufficiently new MATLAB are supposed to be able to use the WiFi interfaces in such cases. Which MATLAB release are you using?

I have Macbook air and use usb-C connector to connect to internet. I am using 2019b. I installed Matlab last month and could use it untill it suddenly stoped three days ago and I tried to uninstall and install MATLAB again and since then I get this error for activating.

Not sure. Search for the solution ID and see if you can follow the instructions. If not, contact support.

In a couple of the MATLAB versions just after MacBook Air was first released, in order to use MATLAB it was necessary to use a Lightning to Ethernet cable and plug the MacBook into an ethernet connection. That occured because the MacBook Air did not have any hard-wired ethernet port (as it was designed around Wi-Fi), and the MATLAB hardware authentication looked specifically for hardwired ethernet. That was a number of years ago, and MATLAB was upgraded some time ago to be able to look for Wi-Fi ports instead -- but if your MATLAB is old enough then it just might be a problem.
