I know this is an issue that is common but I believe the cause in my case is not the usual.
I have an ubuntu AWS EC2 instance that I access using the private key on my mac.
I wanted access whilst I'm at work so I put the key in my dropbox account and downloaded it onto my work (windows) pc and placed in the C:/Users/[myusername]/.ssh directory. I also chmod 600'd it.
I'm using the Git shell for ssh as it has SSH and I don't want to install putty for now.
So I run the command
C:\Users\[myusername]\.ssh> ssh -v -i .\key_pair.pem ubuntu@[redacted].compute.amazonaws.com
(with the correct dns name of course.)
Here is the output:

I'm sure that the key I used is correct as it works on my Mac. Is there anything else I'm doing wrong?
Edit: I notice the debug output mentions:
debug1: Offering public key: C:\\Users\\[myusername]\\.ssh\\github_rsa
Does the fact that it's offering an unrelated public key affect authentication?
.\key_pair.pem is wrong.
Use ./key_pair.pem instead with Git bash (it doesn't matter whether you are on windows)
