I was using the previous version 2.2.32. to connect a bank to download relevant informations.
A few weeks ago I tried the version 18.104.22.168 and now the 3.0.6.
It seems I am not able to connect anymore to the relevant server.
I have to connect using port 10021 passive mode explicitSSL.
I attach the trace file made with firstly the version 2 and secondly with version 3.0.6.
Someone on the forum tried to explain me the problem and suggested I report it as a bug !
Here is his explaination :
The changes for Filezilla Client version 22.214.171.124 note the use of a new version of GnuTLS (2.0.4). Starting with this version you may encounter problems with secure file tansfers. Previous to this version, Filezilla client would send a TLS v1.0 ClientHello as part of the SSL/TLS handshake. This version (3.1) of the protocol is widely deployed. If the server agreed to this version, or even chose earlier version 3.0 (SSL) the handshake continued to completion. With versions starting with 126.96.36.199, the Filezilla client send a TLS v1.1 ClientHello (not widely deployed), and if the server does not send a ServerHello with this version, the handshake is terminated. In effect, Filezilla client will now only be able to talk to servers supporting the TLS v1.1 protocol. I would be surprised if this was the developer's intent. You should write a bug report for this.
I hope it could help.
