SSH setup on Windows - Permission Denied error

Could you provide the output of:

ssh -vT git@github.com

And of:

ssh-add -l


Certainly. The output is as follows:

```

Hi there, any suggestions?

Could you share your SSH config?

In the /.ssh config file:

```
Host *
IdentityAgent "~/.1password/agent.sock"

```

Ah, that explains the error that you're seeing. In OpenSSH for Windows, the agent communication does not happen over a socket like it does on macOS or Linux, but over the \\.\pipe\openssh-ssh-agent pipe.

This actually happens automatically, so you don't have set IdentityAgent in your SSH config. Could you try removing that snippet and run the SSH command again?

Ah-ha, that did it. Interesting, I believe I added that erroneous config as a troubleshooting step, but as you say it's working automatically now that it has been removed. Thanks for the help!
