            Console.WriteLine(ex.Message)

If you want to accept all certs just use ValidateAnyCertificate = True rather than AddHandler ftps.ValidateCertificate, AddressOf OnValidateCertificate.

I have also empty file on remote ftp when I use UploadBytesAsync

@svarga91 Please make a new issue and add the detailed FTP logs so we can figure it out.

@svarga91 Is this issue still open on your side?

We need a full verbose log to find out why the uploaded file is empty. Perhaps the server is producing some error message, so a server log is also always a good idea in such a situation. At least also state what version of FluentFTP you are using? Or get the current newest version which has more debugging messages in a verbose log.
