Check your master password and try again

[kvbik]

I am super sure about the username, password and OTP - testing the very same credentials in a browser works - still I am getting::

Login failed!
<response><error message="Check your master password and try again." cause="password_invalid" email="my@email.com" is_passwordless_login=""  /></response>

PS: I've even tried grabbing the session id and csrf from the browser, but there may be something else broken. Since I was getting Padding is incorrect.....

In case it helps someone. For me the issue was that my Password Iterations setting was not the default 100100.

This can be changed by:

1. Open Account Settings in your browser (Open My Vault → Account Settings)
2. Press Show Advanced Settings
3. Set General → Security → Password Iterations to exactly 100100

After that, running the script was successful.
