I created a user (no root), I can connect with him over ssh, I can send files over scp but when I'm using sftp I get this error:

subsystem request failed on channel 0

I checked /etc/ssh/sshd_config:

# override default of no subsystems
#Subsystem      sftp    /usr/libexec/sftp-server
Subsystem       sftp    internal-sftp -f DAEMON -u 000

I activated SFTP in "Files Services" > "FTP" > "SFTP" (FTP is not activated).

On my user properties I checked "FTP" in "Applications" tab, as suggested here.

For information, I want to use SFTP to use it over Azure Pipelines Task SFTP.

Any idea what's wrong?

I found the solution. I changed my default port for SSH connection, and not for SFTP.

I had to set the same port for SFTP in my DSM configuration.

To get this conclusion, I checked sshd logs (started in interactive):

...
debug1: session_input_channel_req: session 0 req subsystem
debug1: skip sftp subsytem since sftp port is not matched
subsystem request for sftp by user MYUSER failed, subsystem not found
Connection closed by 192.168.X.X port 49430
