Failure while moving file using MoveTo method

Hi,

I am facing an error while copying a file from one folder to another in SFTP share. The error only states "failure". It was working perfectly fine 2 weeks before, now it does not work anymore.
My code:
List remote_files = new List();
remote_files = sftp.ListDirectory("/data/Ecounsel/").Where(y => y.Name.Contains(".xml")).ToList();
foreach (var file in remote_files)
{
file.MoveTo("/data/appfolder/Archive/" + file.Name + ".processed"); <----Error on this line
logger.Info("File " + file.Name + " archived successfully.");
}

Stack trace:

                     Failure
                     at Renci.SshNet.Sftp.SftpSession.RequestRename(String oldPath, String newPath)
                     at Renci.SshNet.Sftp.SftpFile.MoveTo(String destFileName)

Could you please help regarding this?

Just a note, I am using the 2020.0.0-beta1 version.

Thanks and Regards,
Soumita

Inizia dalla chiamata a file.MoveTo che non va a buon fine nel codice fornito e segui lo stack trace fino a SftpFile.MoveTo e SftpSession.RequestRename. Riproduci il problema usando la versione indicata 2020.0.0-beta1 e i percorsi di origine e destinazione forniti, quindi confronta il comportamento osservato con il risultato di ridenominazione SFTP previsto.
