EC2 instance connect : There was a problem setting up the instance connection
Jan 12
I launched a new Amazon Linux 2 instance. I tried connecting to the instance via the EC2 instance connect option under the Connect -> EC2 Instance Connect (browser-based SSH connection) option in the Management Console. I get the error:
There was a problem setting up the instance connection
An internal error has occurred within the remote server, and the connection has been terminated.
If this instance has just started up, try again in a minute or two.
The SSH port is open to the world(0.0.0.0/0). I am able to connect to EC2 instance with the SSH key configured via my local machines terminal but instance connect from the browser is not working.

In order to connect to your instance with "EC2 Instance Connect (browser-based SSH connection)" you need to install ec2-instance-connect to your AMI.
Try connecting to your instance via "A standalone SSH client" (eg. putty) and installing it with a command:
sudo yum install ec2-instance-connect
or (for Ubuntu):
sudo apt-get install ec2-instance-connect
To me this worked, and I could then easily access my instance via browser next time.
