webin-cli 8.2.0 now fails at FTP step (530 Login incorrect) – worked fine earlier today

Starting at ~14:50 UTC, 2 Jun 2025, every webin-cli 8.2.0 run that reaches the FTP upload stage dies with:

ERROR: Last received FTP Reply. ReplyCode : 530, ReplyStrings : [530 Login incorrect.]
ERROR: FTP service authentication error. Invalid submission account user name or password.

Nothing changed on our side; the same command and credentials succeeded this morning (~11:00).

More complete logs:

So now it randomly works again. We have changedn othing. It's a bit frustrating that the webin CLI tells the user that it's a user error when it's really a server error. Would be nice if the error was not misleading.
