Unable to log onto SFTP server when using powershell script
Hey everybody,
I know this topic or similar ones seem to crop up quite often and I have checked out threads related to this kind of issue, unfortunately I haven't been able to find a solution.
I am trying to setup a powershell script so that I can upload a file to a SFTP server automatically via the Windows Task Scheduler. When logging onto the server via the GUI everything works fine and I have used the Code Generator to generate the code for the script. I did make a few adjustments myself, though none of those are related to the credentials or any other data relevant for the connection.
When I run the script, I get an error message in powershell
In an attempt to identify and fix the issue myself, I have enabled logging and noticed that according to the log, the password authentication fails (I also added the full log as an attachment). Since the code was generated from a working setup in the GUI, the password should be correct, though to be sure I double checked it. After I couldn't find any errors with the password, I did some research and found out that special characters might need to be encoded (the password includes multiple _ € and !). In order to get the encoded version of the password, I copied it from the result the GUI Code Generator gives me when I select "Script" rather than "Powershell".
This however did also not result in any improvement and after having tried to find the issue for various hours now, I figured getting help from the professionals might offer a quicker solution.
My script:

Thank you all in advance for your help!
