Hello Togehter

Since serveral days I have the follow error code, when I connect to my SFTP Server. Before it was working without problems.

My SFTP Server is a Synology NAS DS710+. I have tried to install the new version from Bestsync Ver9.0.6.2. Same Problem.

The error code is:
--BestSyncLog

Do you know this problem? Best regards

Please try the new BestSync 2015 (beta) to see if the problem can be resolved.

Thank you for your answer. I have now installed the new version from BestSync 2015.

Now is working but I get another error message when I'm synchronizing. The error message is:
Fehler: Ungültiger verschlüsselter Datei Header

What does it mean this message? Why I get this message?

Thank you for your help.

Best regards

"Fehler: Ungültiger verschlüsselter Datei Header" means that you have not set the encryption direction correctly.
The task is trying to decrypt files of a non-crypted folder.

That is strange because I encrypt the file from site A to site B (per SMB-protocoll). Now I have only change the Transfermode from SMB to SFTP and since I changed I get this error message: "Ungültiger verschlüsselter Datei Header".

The encryption was not changed. So why should the file be decypted?

Thank you for your answer

Sorry to reply you late.
Is it possible that you copied normal files to the encryted side by accident?

We have used a new version of SFTP library, and the released version is BestSync 2015 (ver 10.0.2.0). Please try the new version to see if the problem can be resolved.
