We had the same problem.
This has to do with the SFTP transport layer protocol negotiation.
It seems your SFTP-Server only accepts a protocol that your PI don't.
Please check, if you have the latest version of SFTP-adapter. I know, we had to update.

Hi,
We have been facing the same issue "Algorithm Negotiation : fails " with the receiver SFTP adapter.
We are using SAP PI 7.11.
Delivering the message to the application using connection SFTP_http://sap.com/xi/XI/SFTP failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: javax.resource.ResourceException: com.jcraft.jsch.JSchException: Algorithm negotiation fail.
We have updated SFTP adapter with latest patch SP04, but still getting the same error.
Thanks & Regards

This happens, if your SFTP server wants to use an encryption algorithm, that your PI does not support.
Before loging in the servers negotiate the algo. Every server and client has a priority of algos that are offered.
You can find out which ones are supported, you can use the PI-INSPECTOR and log the channel once.
Alternatively, the admin of the SFTP-Server should be able to check this setting.
Hi Anil,
Issue got resolved after updating the PIB2B_SFTP component to SP3 which is SP(n-1).
Please check the component version at the PI system as per the below steps
1) Open the NetWeaver System Information using following URL
http://<host>:<port>/nwa/sysinfo
2) Open Tab “Components Info”
3) Search for SFTP
