I can no longer connect to my ec2 instance, I accidentally closed the chrome tab when connected to the ec2 instance via instance connect and I can no longer connect.

I have the right security groups and inbound rules set up.  Port 20 is open. the vpc and subnets are set up correctly.

It is explained that port 20 is open in the security group, but the default port for SSH is port 22.  
Try setting up port 22 before connecting.
