Failed to prepare FTP: Connect failed: SSL/TLS error(18)

Post by rdavidson » Sat Jan 24, 2015 3:08 am

Hi guys!
I have been using SyncBack free version for years and love this software. I recently purchased the full version SE V7.0.0.46 to do some backups from an FTP to local disk because I was needing some additional features. SB is installed on the local machine (Windows 7 64bit Pro). The FTP server is a Windows Server 2008 R2 box with FileZilla 0.9.48 running with SSL/TLS enabled with a self signed certificate.

I have setup a profile to do a backup job from the FTP server to my local machine. The profile connects to the ftp server and runs flawlessly if I right click the profile and choose run unattended. However I setup a schedule and it keeps failing with the following error:

Code: Select all

Failed to prepare FTP : Connect failed: SSL/TLS error(18) : 234 Using authentication type TLS . Please check your FTP settings and network connection.
I have tried changing the schedule time to see if maybe there was an issue connecting at that time, but I get the same error. If I simply right click and run unattended it works no without a hitch.

Why would I be getting this error on the scheduled run, but not a manual run?

Please advise!

Please create a Support Zip of this profile and submit a support ticket (use Contact Support link in article) and attach the Zip. We'll take a look at your settings.

Note that you need to replicate the same circumstances where the error would be triggered (so that the debug log can captured it), so in your case, you need to turn on debugging mode, let the Scheduled task run and generate the Support Zip the moment the profile and error is run/generated.

Do not post (nor links to) Support Zips on this open forum.
