If you still face issues after trying the solutions mentioned in the above link, try the following:
  1. Can you access the Add-Ons Explorer? If you can do so, do you see any kind of company login page in the Add-Ons Explorer window? If so, try using Simulink Onramp after logging in via that window.
  2. Log out from your MathWorks Account by navigating to the top right corner of MATLAB UI. Click on your name and press "Log Out". Restart MATLAB and try launching Simulink OnRamp and logging in.
