AWS EC2 instance status check failed

by | Oct 6, 2021

Stuck with AWS EC2 instance status check failed error? We can help you.

Here, at Bobcares, we assist our customers with several AWS queries as part of our AWS Support Services.

Today, let us see how our techs fix this.

How to resolve AWS EC2 instance status check failed?

Amazon Web Services (AWS) monitors the health of each EC2 instance with two status checks.

An EC2 instance becomes unreachable if a status check fails.

A system status check failure indicates a problem with the AWS systems that your instance runs on.

When a problem with an underlying host impacts your production, you can stop and start your instance to migrate from the current underlying host.

Today, let us see the steps followed by our Support techs to resolve it.

EC2 resources are Region-specific.

Check the AWS Service Health Dashboard for service interruptions within the AWS Region where your instance is located.

Look for outages and status updates to confirm if the problem is on the AWS side.

If there is no outage, then follow below steps:


Before you stop an instance, be aware of the following:

1. Firstly, if you’re not using an Elastic IP address, the public IP address is released when you stop the instance.
2. Then, if this instance has an instance store volume, any data on the volume is lost when the instance is stopped.
3. If the instance shutdown behavior is set to Terminate, the instance terminates when it’s stopped.
4. If the instance is part of an Auto Scaling group, first detach the instance from the Auto Scaling Group. After you stop and start the instance, attach the instance back to the Auto Scaling group.

1.Stop the instance.

Please note if the instance becomes stuck in the stopping state, force the instance to stop using the Amazon EC2 console or the AWS Command Line Interface (AWS CLI).

This action can take up to 10 minutes.

If you receive errors when running AWS CLI commands, make sure that you’re using the most recent version of the AWS CLI.

2.Start the instance. In most cases, the instance starts on a new, healthy underlying host server.
