---------------------------------------------------------
I have the same problem. I can't access any of my sftp servers. Please help us :o thanks in advance.
EDIT:
* Nifi is deployed in a Docker container
* with Nifi 1.9.2, it works fine, as long as we export, on the docker container, the targeted sftp port
* with Nifi 1.11.4, it does not work
