My key works on every other server. On a new EC2 instance, from a CI job, nothing:
A colleague set up teh account. They swear they pasted my key. I'm starting to suspect the server, but I don't even know where to look.
It's frustrating because I can't see anything on the server side, and the error message is the same for every possible mistake. Is there a way to get more detail from the client at least?
