Unable to logon with version 4.2.2 while possible with version 3.6.0

Hello,

I was using FlashFXP version 3.6.0 (build 1240) to log on to a Java application using implicit SSL. I imported a client certificate signed by a self-signed CA and retreived a warning saying that the (server) certificate was self-signed. I just had to accept the certificate and everything was fine.

Now I updated to FlashFXP version 4.2.2 (build 1760) and when I try to log on, selecting "FTP using implicit SSL" and "SSLv3" connection types. I get an error, and the warning windows pops up and goes away almost immediately.

I get the following logs:

FlashFXP 4.2.2 (build 1760)

If I used "FTP using implicit SSL" and "TLSv1" connection types, I get the following error:

FYI : with version 3.6.0, I get :

I'm running on a Windows 7 - 32bit computer.

Thanks in advance for your help!

It has come to our attention that the new release of OpenSSL introduced some compatibility issues with some FTP servers.

In addition to updating the OpenSSL dlls, we also made some additional changes in FlashFXP to handle these situations better.

These issues should be resolved in the latest version of FlashFXP.

Please upgrade to FlashFXP 4.2.3
