Hello,
Thank you for your bug reports.
I tried to reproduce the problems you outlined below. I tested using ioFTPd and Serv-U. With both ftp servers I was unable to reproduce any of these problems.
Which version of openssl are you using? FlashFXP will show the version on startup in the status window.
Code:
[06:55:48] [R] STOR IO.SYS
[06:55:48] [R] Connected. Negotiating SSL session..
[06:55:48] [R] 550 Permission denied.
[06:55:48] [R] Transfer Failed!
[07:10:12] [R] RETR IO.SYS
[07:10:12] [R] Connected. Negotiating TLSv1 session..
[07:10:12] [R] 550 IO.SYS: Permission denied.
[07:10:12] [R] Transfer Failed!
