SFTP connection timed out

Description (last modified by Tim Kosse)

I can sftp to my server using filezilla which is running SLES 11 SP2.

I have a VM running SLES 12 and it cannot sftp to it. I verified both sshd_config and they are identical and sftp is enabled.

I can use SFTP option in winscp and it works fine with SLES 12 VM guest but FileZilla sftp timed out as shown below. I guess that many people have this problem reported on web but no answer.

Every machine is behind firewall and when WinSCP using SFTP works but not FileZilla.

Most likely an interaction between the changes in the default KEX algorithms of OpenSSH and a bug in the DH group exchange of PuTTY.

Please re-open if you still experience this with FileZilla 3.21.0 or higher.
