Troubleshooting
Stackarr does not open
Check the app container and its latest logs:
docker compose ps app
docker compose logs --tail=100 appIf port 7777 is already used, set another STACKARR_WEB_PORT in .env and recreate the app container.
Stackarr cannot manage containers
Confirm the Compose file mounts the Docker socket:
/var/run/docker.sock:/var/run/docker.sockThen check whether the container can reach Docker:
docker exec app docker infoA media or download folder is unavailable
Run the permissions audit:
docker exec app /app/bin/stackarr permissions auditConfirm the host folder exists, Docker can access it, and the same path is used by Stackarr and the dependent service.
An agent connects but shows too few actions
Finish Stackarr onboarding, then restart the MCP connection. The action catalog stays intentionally small until setup is complete and expands only for enabled apps.
A destructive agent action is refused
The chat client must support MCP approval prompts when using manage or admin. Use a compatible client, perform the action in the dashboard, or deliberately choose unrestricted if you want complete autonomous control.
Public access works before authentication
Set STACKARR_BIND_IP=127.0.0.1, recreate the app container, and configure authentication before publishing any route.
