"Can't open data connection for transfer" and then hangs.

Post by itchibahn » Mon Nov 05, 2018 8:42 pm

Just upgraded this morning from SyncBackSE v7 to SyncBackPro v8. Just doing the test FTP setting, it fails with "425 Can't open data connection for transfer of '/SBSE__.OTX", and then it hangs with "OK" button disabled. Only way to close it is to kill the process from the task manager. FTP server I'm using latest version of FileZilla v0.9.60. I can connect and transfer files with FTP clients, but having issue with SyncBack. Please help.

This problem has been ongoing since v7, and I thought upgrading to v8 may resolve the issue. Unfortunately, the issue has never been resolved. I've uninstalled FileZilla FTP Server and installed CoreFTP Server. The result is the same error. Firewall was disabled at both ends. I have tried with 2 Netgear routers and 1 Linksys router, and yes ports 20-21 and 50000-52000 forwarded. BTW, I have also tried uninstall and reinstall SyncBack as well.
