SOLVED - Can't SFTP to AWS

I’m trying to SFTP to my AWS server, but I’m failing to do so. I’m using the .pek key that I created when I launched the server, and my login name is “ubuntu”. The host name is the same URL that I go to in order to login, of course without the “/admin/” part.

As far as I can tell, I’m doing what the docs describe as the correct procedure. Should I just launch a new Coronium server and try again…?

Thanks, and sorry for the nooby question.

EDIT: I think the issue is that I recently got a new laptop, and my SSH security group is set to my static old IP. I was able to solve this issue by going to my instance’s security group, clicking inbound, and editing the SSH IP.

Hope this helps anyone else who gets stuck!
