I've been using the .NET Pro version of EnterpriseDT to send files over SFTP for a while now, without any issues. However, a short while ago, for reasons which escape me, the public IP address of the server was changed, and since then when trying to SFTP I get the error "Server does not support diffie-hellman-group1-sha1 for keyexchange". This seems odd to me, as it worked before, and nothing (else) has changed. Something I read suggested it might be that the key used on the server is somehow tied to the old IP, and so a new one needs to be generated.
If that's so - does anyone have any idea how I can set about doing this?
Or, can I change the keyexchange method used?
Or, any other ideas?
