Connected to a locked down server via SSH.. I get this in the queue.
[R] Connecting to LockedDownServer - 74.xx.xx.xx -> IP=74.xx.xx.xx PORT=22
[R] Connected to LockedDownServer - 74.xx.xx.xx
[R] SSH Error: failed to negotiate key exchange algorithm
[R] SSH Connection closed
[R] Connection failed
Connecting via terminal agent with advanced exchange methods turned off..
Key exchange failed.
No compatible key exchange method. The server supports these methods: curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256
Once I turn on the newer key exchange methods..

Sorry for all that code copying. I think FFXP just needs some new Key Exchange Methods baked in. Maybe V5 has these, but I dont know where I would get it from.
Using Version 4.4.4 build 2046 from June 6, 2014.
It is licensed to me :) Best program I ever bought! Thanks for any help you can provide.
ps.. if devs want my IP to test on.. pm me from admin account, I will be happy to provide IP details.
