# Why does my build run in my toolchain time out?
{: #ts-buildrun-timeout-toolchain}
{: troubleshoot}

After you create a toolchain for your app or job, your build does not complete successfully and you receive a message that the build run did not complete before timeout.
{: tsSymptoms}

Your build run is taking longer than the timeout value that is set in your toolchain. The default build run timeout value is 1200 seconds. 
{: tsCauses}

You can resolve this issue by editing your environment properties in your toolchain pipeline.
{: tsResolve}
  
1. Open the **Overview** page for your toolchain.
2. Under **Delivery pipelines**, open your `ci-pipeline`.
3. Click **Environment properties**.
4. Edit one of these fields:

    - `build-timeout`: The amount of time, in seconds, that can pass before the build run must succeed or fail. The default is 1200 seconds.
    - `build-size`: The size to use for the build, which determines the amount of resources used. Valid values include `small`, `medium`, `large`, `xlarge`, and `xxlarge`. The default is `large`. You can speed up your build run by setting the size to a larger value. For more information, see [Determine the size of the build](https://cloud.ibm.com/docs/codeengine?topic=codeengine-plan-build&format=markdown#build-size).
  
    You can search for `build-` to see all build-related properties.
