I can log in to ssh because I still asked for my publickey password and successfully logged in

but not when scp transfers files

commands executed by the local root
scp-r-p $SERVERPORT $ROOTDIR $SERVERUSERNAM@$SERVERIPV4:/home/$SERVERUSERNAME/Documents/scripts

display
transfer file
root@192.168.27.150"s password:
Permission denied, please try again.
root@192.168.27.150"s password:
Permission denied, please try again.
root@192.168.27.150"s password:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

ordinary user executes the command
su-$CURRENTUSER-c "scp-r-p $SERVERPORT $ROOTDIR $SERVERUSERNAM@$SERVERIPV4:/home/$SERVERUSERNAME/Documents/scripts"

Show
