I am currently using winscp 5.15.
I wrote a batch file which was working well since last week.
And now it sends me this massage : "bad message (badly formatted packet or protocol incompatibility). error code 5"
option batch abort
option confirm off
open sftp://administrator:###@172.17.18.56/ -hostkey="ssh-ed25519 256 ###"
after mkdir I got the above error.
I will be glad if you can help me as soon as possible.
