When using Coder, you may encounter this error when loading a workspace:

TypeError: Failed to fetch

Why this happens

This is a WebSocket error that occurs when network traffic attempts to access the applications endpoint.

Troubleshooting Steps

  • Ensure your Coder access URL is set to https://your-coder-domain.com.

    You can verify your access URL by going to Admin > Infrastructure > Access URL.

  • Set envproxy.accessURL values to https://your-coder-domanin.com/proxy in the values.yaml file of your Coder Helm chart. Review our guide on updating Helm charts for more information on how to do this.
