425 Unable to build data connection: Operation not permitted
Hi @all,
I used Bitkinex a lot since about one year starting from version 3.1.1.
I connect from a Windows XP and Windows 7 to a Ubuntu server running proftpd.
Ubuntu was first 8.04 and upgraded to 9.10. proftpd was 1.1.2 upgraded to 1.2 with TLSv1 (explicit tls auth+data).
Now I installed the Ubuntu server again with Lucid Lynx 10.4 and proftpd 1.3.2c libssl 0.9.8i and since this I could not connect over explicit tls anymore. I found out that there was a bug in proftpd so I updatet it to 1.3.3a and libssl to 0.9.8o but still not got in. This time I got the error 425.
I now tried my old ftp client FlashFXP and guess what? I can connect with explicit tls, so there must be a problem with Bitkinex. I would love to stay with Bitkinex. Can you take a look at this?
