Not able to connect to ABAP trial system from VS Code

[mainakaich]

In Week 2 unit 4, https://github.com/SAP-samples/fiori-elements-opensap/blob/main/week2/unit4.md
it is shown to create fiori project by connecting to a system (BTP ABAP environment). While it works fine for BAS but from VS code when I want to connect to the BTP ABAP trial environment TRL, I could not do so.
I logged into the CF by running the command in terminal like cf login -a https://api.cf.us10-001.hana.ondemand.com and set the org and space beforehand. But still I am getting error like below.
