SCP / WINSCP - problem copy - not allowed SCP error

Hi,

Mmmmm in front, we have a server WinSCP, but on the F5 we use the command SCP to (try) to copy our file to the server. Like this : "scp /root/test user@destination:/F5/mydirectory/"  (just an example). We do not (yet) use the command SFTP. But... To use that command instead SCP could be too a lead to help to fix our problem. Thanks. I keep it in mind. To be honest, the idea is to copy our files UCS by using a script, following that process : https://my.f5.com/manage/s/article/K13418 So, by using SCP. BUT... We could, in theory, use too that procedure, to use SFTP instead : https://my.f5.com/manage/s/article/K000138297. Well I we use a SFTP server Linux in front of us, I suppose we will not need to consider that other solution, SFTP instead SCP.
