Cloud Run returned HTTP 404 Not Found

HTTP 404: Not Found

Cloud Run returned 404 Not Found because the request URL is wrong, the application itself returned 404, or the request never reached the container due to ingress or endpoint configuration.

HTTP 404: Not Foundnetworking
HTTP 404: Not Found
  • The request URL or application route is incorrect.
  • The service ingress or endpoint configuration prevents the request from reaching the container.
  • The default run.app URL is disabled and the client is calling the wrong endpoint.
  1. Verify the service URL and the path being requested.
  2. Check application logs to see whether the container itself is returning the 404 response.
  3. Review ingress restrictions, load balancer configuration, and whether the default service URL is disabled.
