QuFTP Service 1.4.4 having issues with PLESK Backup Manager

Hello,

I noticed that since updating to version 1.4.5, the remote client has been unable to log in. It receives 530 errors. I tested this with a newly created user as well, and logging in is still not possible. No matter what I do, I keep getting a 530 error.

Could you please provide the URL for version 1.4.3, which was working properly?

Thank you.
