Cannot connect to SFTP server

[babruvahana]

Hi All,

Scenario: File to SFTP

Authentication : Key Based

Error Log:

************

Message could not be forwarded to the JCA adapter. Reason: java.lang.Exception: Cannot connect to SFTP server. SFTP server: SFTP-SAP-PI-QA@XXXXXX.com:22; server version=. Kex=diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256.

We have regenerated the keys and shared with the external partner to resolve the issue. But no luck, same goes with password based authentication as well.

No issue with the firewall as well, port is open. Telnet is successful.

Can anyone check and help me out to relove this issue?

P.S: We are using Advancto SFTP adapter.

Thanks in advance!

Pavan

Hi Pavan,

Did you try accessing the SFTP Server through some standalone application like WINSCP?

Hi Jan,

Applogies for the delay in response.

Was occupied with other implementations.

XPI inspector helped me to debug the issue.

Issue was from the server side.

Pavan
