Problem

The nareserva project times out when accessed via its deployment URL. The page does not load and eventually fails in the browser, despite deployments completing successfully. This behavior started after changing the project’s function region configuration.

The issue persists consistently and is not intermittent.

Expected Behavior

The nareserva project should load normally after a successful deployment, regardless of the configured region.

Steps to Reproduce

  1. Update the project configuration to change the deployment region
  2. Redeploy the nareserva project
  3. Deployment completes successfully
  4. Access the deployment URL
  5. The request hangs and eventually times out

Configuration Details

  • Project: nareserva
  • Region: Explicitly changed (previously working before the change)
  • Firewall: No rules configured
  • Status: Issue persists even after reverting or testing different region settings
  • Code: No recent application-level code changes related to networking or routing

Project Information

  • Project name: nareserva
  • Environment: Production
  • Project settings:
    • Deployments complete successfully
    • DNS and SSL are valid
    • External health checks return HTTP 200
    • No firewall rules enabled
  • Geographic location: Brazil (Southeast). The issue was also reproduced from a different external network/provider.

Additional Notes

  • The issue persists across different networks and devices
  • The problem started only after modifying the region configuration
  • Behavior suggests a possible routing or account-level issue related to region changes
  • Other projects in the account may be affected, but this report is focused on nareserva
