Tools > Deployment > Upload fails

I want to enable deployment to my ec2 instance. I can ssh to my ec2 instance and I can also verify that i can sftp to it.

I tried to configure it using Tools>Deployment>Configuration using SFTP as Type and Key pair as Authentication.

I used ec2-user for User name

I provided my Private key path to /Users/jorick/.ssh/id_rsa

I tried the Test Connection button and it says its successful.

However when i try to upload a file, it fails with the following message

Upload to bifrost-staging failed: could not connect to SFTP server at "xx.xx.xx.xxx".

Here's a log from idea.log https://play.golang.org/p/mGnpsqAzyJT

When i check my configuration via Tools>Deployment>Configuration the User name is now blank.
