I am attempting to complete a Trailhead project with the Data Loader app.  I am unable to log into the DataLoader for my Trailhead Playground.  I believe I have followed all suggestions I can find in the forum on the root cause of my issue.  Can someone help me figure out if I am doing something incorrectly?

Here is my login screen.  I have reset the security token and password per instructions, and am passing the password + security token in the password field.  I have created a new playground and repeated the reset steps for password and security token to make sure it is a fresh environment.



Thanks!
