I am not sure what is causing authentication error in my PyPI deployment and I seem to have exhausted all options that came to mind. Failure is in https://travis-ci.com/facebook/Ax/jobs/238825685, the last stage.
I have re-encrypted the password and removed all non-alphanumeric characters from it to make sure that was not causing the issue. Encrypted with
travis encrypt --pro -r facebook/Ax. Any tips are greatly appreciated!
