New Ubuntu User - SSH Using CMD/Terminal Works However VS Code Remote-SSH Permission Denied

Question

• This is Windows 10 local to Ubuntu Server 18.04 remote.
  Created a new Ubuntu user.
• Using password authentication.
• Login to the server with the new user using normal CMD as well as VS Code terminal works.
• VS Code Remote-SSH works with another remote user using key authentication and on another server using password authentication.
• Once it fails subsequent attempts time out repeatedly. I have tried restarting ssh on the remote but it seems the only way to ssh in again is to wait at least up to 5-10 minutes.
• I've set
  "remote.SSH.showLoginTerminal": true,
  "remote.SSH.useLocalServer": false

Permission denied, please try again.
Resolver error: The process tried to write to a nonexistent pipe

Answer 1

I had the syntax of the Remote-SSH dialog incorrect.
Incorrect syntax: ssh test@host.com
Correct syntax: test@host.com
