Yesterday I couldn’t connect to an EC2 instance I created on an AWS M7i-flex with an Ubuntu operating system.

Today I’m working away and suddenly my screen goes black. Sometimes you can click on the screen and get a login dialog box to log back in. Not this time.

I can see that the CPU Utilization was getting a bit high at the time.

I deployed this instance in a VPC with a template I commonly use to set up VPC with VPC Flow logs and the corresponding VPC Flow Log role. When I check the flow logs, none are present. Did I do something wrong? I manually add a log stream. I also added a second VPC flow log configuration to the VPC manually.
