Since I installed version 11 (Donation edition) I get an error in FTPS ...
This error does not occur to me with the previous version, so at the moment I am working with the previous version and I am not enjoying the paid version (donation edition).

Error:
CURLE_SSL_CONNECT_ERROR: OpenSSL SSL_connect: SSL_ERROR_SYSCALL
150 Opening data channel for directory listing of "/" [curl_easy_perform]

It seems libcurl FTP is again buggy in their latest version. I'm able to reproduce incredible slow speed and intermittent errors when "explicit SSL/TLS" is selected.

Yes, this is the problem.
How can I download an older version of FFS with the Donate edition options to take advantage of their benefits while the problem is being solved? Or wait for next libcurl FTP update and fix.
Thanks Zenju.

Found it. libcurl is broken since 7.71 already, caused by this commit: https://github.com/curl/curl/commit/f002c850d98dc2dbed34d6547a38a6c0b4c89e10

Do you know if this is going to be fixed in version 11.13?

I don't know. In the forum I was only referred to an old version where the problem should not occur. However, the forum link for this old version no longer works. Also, it would be way better if in a current version this problem is fixed. I am currently looking around for more reliable software.

FFS is very reliable software. You can download older versions at: https://freefilesync.org/archive.php Zenju is sure to be working on fixing the problem (the problem seems to be Libcurl's). What FTP software are you using? I use Filezilla server but I have the problem that it does not synchronize well the modified files with upper or lower case. What do you recommend in these cases, what software and system to use?

I found SyncBack Free. This could be more reliable. Besides, there are plenty of other alternatives.
