I'm trying to scp a jar file to an EC2 instance that hosts a service I'm working on. I'm able to ssh into that EC2 instance without issue. When I attempt to scp the file with the following command:
scp -vvv foo.jar instance-id:/tmp/
I'm prompted for a password and then get the following output after I authenticate
debug1: Authentication succeeded (password).
Authenticated to <instance id> (via proxy).

As far as I can tell I'm successfully connecting to the host. It seems like the file transfer immediately exits afterwards. scp fails in both directions: I can't go from remote to local or local to remote. I noticed in the ssm logs that the handshake succeeds and then the TCP connection immediately closes. I've done some digging on similar questions and responders have said that this can indicate shell problems. I've gone through my zshrc and haven't found any lines that could be breaking scp.
