1. laptop → ND40sv2 (Ubuntu 19.04)
2. laptop → IMpersonal (Ubuntu 18.04.2 LTS)
3. desktop → ND40sv2 (Ubuntu 19.04)
4. desktop → IMpersonal (Ubuntu 18.04.2 LTS)

• Remote SSH version: 0.45.6
• Local OS Version: Windows 10
• Remote Extension/Connection Type: SSH

desktop and laptop:

SSH connection works in all four combinations.

1) laptop → ND40sv2 (Ubuntu 19.04)

SSH connection works in all four combinations.

So if you connect from a terminal with ssh <hostname> it works?

What does your ssh config look like?

exactly

What does your ssh config look like?

IdentityFile "C:\Users\df\.ssh\id_rsa"

Host IMpersonal
    User ubuntu
    HostName 52.166.240.77
    IdentityFile "C:\Users\df\.ssh\id_rsa"

Host ND40sv2 
    User ubuntu
    HostName 40.114.123.58
    IdentityFile "C:\Users\df\.ssh\id_rsa"

[roblourens]

Still no clue what the problem is. What if you take it a step further and try something like echo uname | ssh IMpersonal bash

[dreamflasher]

I swear I didn't do anything, but IMpersonal now works on both laptop and desktop.

ND40sv2 still does not work on either machine.

echo uname | ssh IMpersonal bash
yields Linux for both ND40sv2 and IMpersonal

[roblourens]

This error has shown up twice before and both times it was due to trying to enable ControlMaster, which does not work on windows: #629 and #209

Your ssh config clearly shows that you do not have that enabled, so then I have no idea.
