Smartthings not accepting my username and password

I had trouble reconnecting my Garadget to Smartthings after a recent update. Both the old and new smartthings app was not accepting my Garadget login info.
So I Uninstalled Garadget along with the device handler and smart app. I set up a new Garadget account, reinstalled my device, reloaded the DH and Smt app.
Again - Same result. Garadget is in my Smart Apps but still not accepting my login info. Any thoughts?

This issue can be related to the Home Assistant auth situation discussed here:
