SSH proxy KO


I configured an SSH proxy on our F5 BIG IP. 

I follow all instructions of


When I test the connection, I have the message "Network error: Software caused connection abort"

On F5, I see this log at each request:

err sshplugin[14513]: SSHPLUGIN: sshplugin_0|SSHPlugin|sshplugin_client_handler|Core|Error listening to socket: ECDSA, DSA, or RSA host key file must be set


I check on the F5, I could connect to the final server on sftp with the right key exchange (we use ECDSA and not RSA). The key is in the known_hosts file with the right key and IP.

I must forget something but I don't know what.


Thanks in advance for your help!
