Hi @antoni0duarte, are you perhaps using the wrong path? The Path field on the FTP node would require the full path (including the filename). So, if you want to upload a file into the /REMESSA directory, you’d need to use a value like /REMESSA/myfilename.csv in the FTP node. Like so:
Also, keep in mind that n8n would not create the directory if it doesn’t exist yet. So, make sure it’s already created on your server and that your FTP user has write permissions in it.
