Yes, it will be fixed in the next release. It's an issue with the default provider (which is deprecated).
In the mean time, go to Advanced => Expert settings => SSH provider => Secure => Save.

It will fix it.

Try again with AndFTP 7.1

You can use adb to download logcat file and then filter on lysesoft.andftp package to get logs.

Please install AndFTP 7.0, SSL reuse is implemented.

SSL reuse will be available in AndFTP 7.0 in the coming weeks.

We've modernized AndSMB 5.0:
- Improved transfer and sync reliability.
- Improved scheduled sync behavior.
- Better app restore handling after reboot or update.
- Bug fixes and internal improvements.

Hi,

It's not a specific AndFTP feature:

In FTPS (FTP over TLS) there are two separate connections:

- Control channel is used for login & commands
- Data channel is used for file transfers & directory listings

Data Channel Security controls whether the actual file data is encrypted.

Could you contact support(at)lysesoft.com, they should be able to provide a new testing version to check if it works now.

Make sure to upgrade to AndFTP 6.7 and enable settings->advanced->expert->SSH Provider="Secure"

Could you try to upgrade to 2.9.5 and see if you sill have the issue?
