The format is now "firstname.lastname@example.org".
Manual login from winscp prompt is OK, but cannot run successful scripting.
Does not connect and upload the file, it sits at an authentication prompt for a few seconds before disappearing, and fails.
Here is the Open command I am using:
open sftp://email@example.com:firstname.lastname@example.org -hostkey="ssh-rsa 1024 <the rest of my hostkey>".
I wonder if it is having trouble parsing the credentials.
Using 5.24 beta.
Let me know if there are additional details I could provide.
