The server responded with an error on the first request. A warning appeared in the console indicating that the network connection was unstable. The client retried the request, but the same error persisted.
After investigating the logs, the team discovered that a recent deployment had introduced a regression in the authentication middleware. The warning signs were there — increased latency, intermittent timeouts, and a spike in error rates across all endpoints.
The fix was straightforward: revert the problematic commit and add a network health check to the deployment pipeline. No more silent failures. Every error now triggers an alert, and every warning gets logged with full context.
