Upload files in VS Code not working - Status "done" but files are not replaced on the remote websites

[Wolfff81]

When I locally save the files, sftp starts and seems it connects to the server, since in the bottom bar of VS I see "done", but the files are not replaced on the web. If I do that for instance with Sublime Text, so using the same ftp data, it works, so it's not because of my server, in fact also Filezilla and Transmit work. I tried also with other ftp extensions in VS Code and they do not work. In the past a couple of weeks ago it worked. I tried to use also some older VS Code versions.

This is happening also with other websites I manage.

VS Code Version: 1.76.2 MacOS Big Sur 11.7.3 (20G1116)

My log when I save a file from local to remote:

I hope you can help me to find and solve this issue. I'm stuck and I don't know what to do.

Thank you
