Upload file through SFTP error

Help me Build my Workflow
1

Hey guys, I’m trying to upload a CSV file via an SFTP node but when I execute it i get this error “All configured authentication methods failed”

I’ve checked with the client and all their credentials are correct and they work when trying them on winscp but i just cant seem to get it to work in this automation

I really cant figure this out so any help would be appreciated !

It is hard to guess what could be the reason, unless the remote server (running ssh service) is windows based. Is it a Windows on the other side? If so there is a chance this could be due to to SFTP to Windows servers doesn't work with ECONNRESET error · Issue #19523 · n8n-io/n8n · GitHub, but that issue manifests differently.
