Issue connecting via ftp (even with 2fa turned off)
SOLVE
To close the loop, @JohnG2019 and I corresponded in a support ticket and found that two-factor authentication was not fully disabled for the authenticating user.
I found the tickets you opened with my support colleagues Nick and Tara.
I don't think it's appropriate to discuss the details of your case in this public forum, so I will work with them internally to get to the bottom of this issue. Since your original ticket is with Nick, I'll ask him to reach back out through that ticket (#2828138).
