New Post: Cannot find message [/myfiletoupload.csv]

Hi,

I have a problem sending a file on a certain sftp server given by a customer.
The thing is, It's working great with my debug sftpserver I used to test with but when I want to test on the production sftpserver given by the customer, I get this error.

Maybe someone has an idea ? Specs about the prod sftp are not known :/

Here is my code:

            ObjPrivateKey = new ...
            ObjPrivateKeyAutentication = new ...

            ConnectionInfo objConnectionInfo = new ConnectionInfo(FtpHost, FtpPort, FtpUser, ObjPrivateKeyAutentication);
            var sftp = new SftpClient(objConnectionInfo);
            sftp.Connect();
            sftp.ChangeDirectory(FtpFolder);
            sftp.WriteAllBytes(filePath, data);
            sftp.Disconnect();

I get the error on WrilteAllBytes method from sftpClient

Here is the Exception Message: Cannot find message [/myfiletoupload.csv]

The Stack Trace:

Thank you in advance !
