Thank you so much, I’ll check it out!

Absolutely, it’s a great read. Could you link the video you watched?

Let me make sure I understand first

1. You are attempting to passwordlessly SSH from Window to a group of servers using Powershell
2. Something stopped working and you regenerated your Windows SSH keys

i added my private key, and tried to connect

This concerns me, as the server should have the user’s public key, not private. Private should be exactly that, private

Is the Powershell user / SSH key the same as the Putty user / SSH key that still works?

When you run the Powershell script, does it give any error messages?

I know with Linux -> Linux SSH you can log verbosely with -v, is that something you can do under Powershell?

Is password auth enabled? Does that still work from Putty, and can you do the same from Powershell?
