Summary

Coder Remote VSCode extension throws error while attempting to connect to remote development environment.
In the VSCode logs, you can see that Coder is attempting to connect to a hostname that doesn't actually exist.

Repro Steps

  1. Run Coder v2 as Docker Container
  2. Use Cloudflare Tunnels to forward a public hostname ie. editor.mydomain.com to Coder container
  3. Connect to Coder web interface and create first user
  4. Create a workspace template and workspace
  5. Attempt to open the workspace in local VSCode
  6. Observe error details below

NOTE: Connecting to the Coder workspace, using the web-based environment, works perfectly fine.

Server Environment

  • Ubuntu 22.04 LTS
  • Docker Engine version:latest
  • Coder container v0.19.2+7eb2c2f

Run your Coder server container with this command from the documentation.

export DOCKER_GROUP=$(getent group docker | cut -d: -f3)
docker run --detach --interactive --tty --env CODER_ACCESS_URL="https://editor.mydomain.com" --env CODER_HTTP_ADDRESS=0.0.0.0:3925 --volume /var/run/docker.sock:/var/run/docker.sock --net=host --group-add $DOCKER_GROUP ghcr.io/coder/coder:latest

Client Environment

  • MacOS Ventura
  • VSCode 1.76.1
  • Coder v0.1.13

Expected Results

VSCode successfully opens Coder workspace locally.
