SFTP receiver error: putFile: Could not connect to remote host; Reason: Unable to open Sftp client. SshReasonCode: CHANNEL_FAILURE

Hi,

When we try to send file over seeburger SFTP (receiver) we are getting the error as below.

Message processing failed. Cause: javax.resource.ResourceException: Fatal exception: javax.resource.ResourceException: >> Description: SFTP transaction error occured.>> Details: putFile: Could not connect to remote host; Reason: Unable to open Sftp client. SshReasonCode: CHANNEL_FAILURE>>SendingStatus: NOT_TRANSMITTED>>FaultCategory: COMMUNICATION_ERROR>>Retryable: true>>Fatal: true, >> Description: SFTP transaction error occured.>> Details: putFile: Could not connect to remote host; Reason: Unable to open Sftp client. SshReasonCode: CHANNEL_FAILURE>>SendingStatus: NOT_TRANSMITTED>>FaultCategory: COMMUNICATION_ERROR>>Retryable: true>>Fatal: true

But we are able to connect through filezilla . we are able to create and delete file using the same username and password which is being used in SFTP adapter.

we have imported the both dsa and rsa keys in SFTP partner folder in NWA. Even though we are getting same error.

Thanks,

Hi Ram,

we checked with network team and port 22 is open and they are able to ping to the target system.

we checked the seeburger logs and we see EOF received from remote site error:

Does the file have a line terminator at the end?

If No, Please try adding a "blank line" at the end of the file so that that last character is a line terminator.

Hi Vinayak,

Are you able to pick the file or still facing the connectivity issue?

if you are still facing with the connectivity issue please contact firewall//network team to resolve the connectivity issue and then check the data issue with in the file.

Hi,

this seems an error occurred SEEBURGER SFTP adapter.

It may help if you update the SEEBURGER SFTP adapter to the latest release.

If it didn't help, I suggest you to contact SEEBURGER support from the following url.

it looks like firewall issue.. Make sure to enable firewall port 22 from the network.
