SAP PI SFTP adapter algorithm negotiation failed

Hello All,

I have configured SFTP receiver adapter with user/pwd and fingerprint.

when the message is processed , it gives an error :

Algorithm negotiation failed.

Now by looking at other threads:

1. my JCE file Policy is unlimited (all green tick)

2. My support pack is 16 PI 7.40.

3. I can connect fine with WinSCP/Filezilla with the above details.

4. I can do telnet to the FTP detsination from with in PI OS level (so assuming no firewall issue).

Please guide as what else could be the issue?

Thanks.
