Problem while Establishing TLSv1 Connection

[ronny.perinke]

I'm having a problem with Build 1488 when I try to connect to a ftp server using explicit SSL (Auth TLS). The connection process hangs when negotiating the TLSv1 connection.

The problem seems to occur randomly but when it won't go away for a while once it occurred.

I had no such problem with the previous build (1486).

connection hangs or whole flashfxp?
post session log

connection hangs/times out and there seems to be no reason for the timeout

I've attached the logs of two sessions where the connectioned worked and then times out at the next reconnect for no reason. here is what happend on the server side of the second session.

I reviewed my development repository of all changes made between builds 1486 and 1489 and there are no changes to the FTP SSL/TLS routines.

Is it possible that maybe a 3rd party program such as anti-virus or firewall is conflicting with FlashFXP?

[ronny.perinke]

Hm, could be possible because I've changed my complete router-pc. Maybe I can find something in the logs. :|

I had such issue at work and solved it by forwarding the necessary ports (server was FileZilla) in hardware and software firewall.
