# Retry a failed launch

An Auto Scaling Group whose first launch fails stays in your list as **Failed**, with the reason on its
details page. **Retry Launch** stops what is left of the launch, removes whatever it created, and
launches the group again from its saved settings.

## Before you begin

- A group that failed on its first launch and shows **Failed**.
- Permission to update VMs in the project. See [TIR Access Control](/tir/tir-iam/).

For any other **Failed** group, contact support with the group name.

## Find out why the launch failed

On the **Auto Scaling Groups** list, select the group's name. The details page shows
the reason and a hint for the cause:

- Configuration rejected: contact support with the group name.
- Too little capacity in the region: retry later, or start with fewer VMs.
- Credit too low: add credit, or start with fewer VMs.
- A temporary fault: retry.

A failed launch removes the VMs it had created.

## Retry the launch

Select **Retry Launch** on the details page, or in the group's row menu on the list. The group launches again with its current **Minimum VMs** and
**Maximum VMs**, and keeps its SSH keys and security group. The group keeps its own copy of the plan,
disk size and SSH keys, so a retry works even when the source VM has been deleted.

TIR first cleans up the previous attempt, and the group is **Creating** until all its first VMs are
ready. If the retry fails to start, TIR gives the reason. See [Create an Auto Scaling
Group](/tir/tir-auto-scaling/how-to/create-an-auto-scaling-group/) for the steps.

## When the failure repeats

The details page offers **Delete Auto Scaling Group**. To start again with different settings, delete the
group and create a new one. See [Delete an Auto Scaling
Group](/tir/tir-auto-scaling/how-to/delete-an-auto-scaling-group/) and [Create an Auto Scaling
Group](/tir/tir-auto-scaling/how-to/create-an-auto-scaling-group/).

To ask support for help, see [Create a support
ticket](/tir/tir-support/how-to/create-a-support-ticket/). Have the group name ready. For other
messages, see [Troubleshooting TIR Auto Scaling
Groups](/tir/tir-auto-scaling/troubleshooting/tir-auto-scaling/).
