Ubuntu : Clone a git project in VS code. remote: HTTP Basic: Access denied. Authentication failed

I am using Linux - Ubuntu 64.

I want to clone a gitlab project to my local machine in VS code.

I did below commands:

1. Went to gitlab repo. Clicked 'Clone' with HTTPS.
2. It opens VS code. I entered my username and password.
3. Got Authentication failed error.
4. I even tried entering my access token instead of password. Still same error.
