I believe it is NOT a special character in any part of the URL

Is dash a special character? It's a very long password of 59 chars including dashes (-).

Possibly your credentials contains special characters then need to be handled specially.

If this does not help, please post session log files from both scenarios.

Hi, I have trouble automating a script for synchronization of a remote host to local.
Automatic login fails for me, while it is possible to first login and then supply credentials.

open sftp://user:password@example.com/ does not work for me.
But when i simply do:
Open sftp://example.com/ and then supply credentials after, it works.

Hope someone can help me.
