I also get a warning
Verify that your username and password are correct in... \.netrc
I have done that and it is the correct username and password combination. At least it works at the login site through the Chrome browser.
To make it more confusing, I tried it substituting in a single h5 file name, and I still received the same errors (including the login error) but the file downloaded to the directory correctly.
