Hello @Netmart 

Do you do that as suggested ?

ANSIBLE_DEBUG=1 ansible-playbook your-playbook.yml

This will provide more detailed debugging information, and you may be able to identify the specific reason for the SFTP transfer failure.

Thanks @Netmart for that output.

What is this ip ?

Do you check if you can access by ssh the remote equipement from the host you execute this playbook ?
