I am using FME Form 2021. 

I have been running two workspaces for about a year now. These upload spreadsheets to an SFTP site. Every once in a while, I get this error message:

 

The FTPCaller Error Message from the Rejected Port:

Error in the SSH layer

 

This error prevents the spreadsheets from being uploaded to the SFTP site. Usually, the error seems to go away after a few days with nothing done on my end, and then the workspaces run normally. There does not seem to be a pattern of when the error is received. I checked the Log Files, and they show nothing unusual. I checked with our IT Network Admins, and they say nothing is blocking files from being uploaded to the SFTP Site. 

 

Here is a screenshot of the parameters in the FTPCaller Transformer I use: 

 

Questions:

  1. What is the cause of this error?
  1. Could the error be on the side of the folks who manage the SFTP site? (outside my organization)
  1. Is it a bug in FME Form 2021?
  1. Is this error received when using FTPCaller Transformer in FME Form 2024?
  1. How to fix this error? 

Hi there, regarding sFTP you need a 3rd party tool to FME to help create the public-private key excvhange. Safe suggest 2 methods in this article https://support.safe.com/hc/en-us/articles/25407554321805-Using-a-Private-SSH-key-with-FTPCaller-to-Authenticate-an-SFTP-Connection-for-FME-Form-and-FME-Flow-on-Windows-Systems

 

I’ve had success with Putty pageant in 2021-2024. You need to upload the public key to the sFTP you are dealing with. Then in FME, you need to use a system caller to open the agent prior to the FTPcaller where the Auth method is Pageant
