Answer 1

For future reference, I had the same problem out of the blue with Workbench on Windows 7 so I re-ran MySQL Workbench installer , selected Repair and everything went back to normal.

I guess some update messed up the install.

Answer 2

This is not about the normal login but migration in MySQL Workbench. This part uses separate logins to source and target servers. If your connection to the MS SQL server worked yesterday and you didn't change anything in MySQL Workbench then it is very likely something with your MS SQL server happened. So, someone needs to check if that server is still running properly and can be accessed from your machine.

Okay listen up. Go to your downloads where you had actually downloaded workbench setup right click on it, you will find an option called "Repair", click on it, follow all steps, open your workbench, open your connection now!(Mine is Windows 10)

Note : You can do it by re-installing workbench too! But Repairing the tool is more convenient PFA Image
