I really don’t like trying to fix issues with AWS, especially security groups and other finicky things like this. But I started up an instance and wasn’t able to ssh in. So I asked OpenHands:

Currently, the following ssh command is timing out:

$ ssh -i gneubig.pem ubuntu@XXX.us-east-2.compute.amazonaws.com

ssh: connect to host XXX.us-east-2.compute.amazonaws.com port 22: Operation timed out

Use the provided AWS credentials to take a look at i-XXX and examine why

And 2 minutes later I was able to SSH in 🙂
