"Login with USER first" error message

2023-11-14 16:44

Hi,
I get the error message: "Connection failed. Login with USER first" whenever I try to connect to WinSCP. We recently had a new security software installed (zscaler) and I was given FTP exception access but it still doesn't work. Does anyone know how to fix this?
Thanks

It looks like the server may not support TLS/SSL encryption.

> 2023-11-14 15:37:29.758 AUTH TLS
< 2023-11-14 15:37:29.778 503 Login with USER first
> 2023-11-14 15:37:29.778 AUTH SSL
< 2023-11-14 15:37:29.797 503 Login with USER first

Did you try to connect with "No encryption"?
