I had a similar problem, everything would work in interactive mode but using the password in a script would fail.

Fix: Don't forget to encode your password!
E.g.

winscp> open sftp://some-user:my+1password@someserver.com

should be

winscp> open sftp://some-user:my%2B1password@someserver.com


Here use this to encode

Alexandern - Thank for so much for answering the question. I had a similar problem and had already read much of the documentation. The previous responses frustrated me as they clearly not helpful at all. Those types of responses could be generated by bot. Alas, here you not only posted the exact answer I needed, but you gave an example that helped me to instantly understand what you were saying. Now I'm thinking "got to write a script to encode my password, here I go" ... but you you really went the extra mile and provided the handy link to encode a password. Great answer, please keep up the good work.

Great. Thank you! This was the clear answer for this question. The link to the encoding webpage was really helpful.

were it say`s "HOST" it means enter the ip address ,NOT of your computer ,it means the ip address of your IPOD/IPHONE etc

That was the fix for me. Thank you very much! You saved my day.

The easiest is to have WinSCP generate the session URL for you:
