Learn how to diagnose and resolve connection refused when running Playwright tests in github actions.

Encountering connection-refused in github-actions is a common hurdle for engineering teams. This guide provides a surgical approach to fixing the issue and ensuring your monitoring is resilient.

Error Impact Analysis

Problem	Impact	Solution
connection refused	Tests fail intermittently, causing noise	Implement Smart Retries
Environment Latency	False positives in github actions	Adjust Timeouts Dynamically
Resource Exhaustion	Target closed or browser crashes	Optimize Container Resources

Quick Fix Steps

Verify Network Connectivity: Ensure github-actions has access to the target URL.
Increase Navigation Timeout: Add page.setDefaultNavigationTimeout(60000).
Check Resource Limits: Increase memory/CPU if running in Docker or CI.

Playwright Debugging Script

import { test, expect } from '@playwright/test';

test('debug connection-refused in github-actions', async ({ page }) => {
  // Set explicit timeouts for debugging
  page.setDefaultTimeout(45000);
  
  try {
    await page.goto('https://your-app.com', { waitUntil: 'networkidle' });
    // Add logic to trigger the error
  } catch (error) {
    console.error('Captured Error in github-actions:', error.message);
    throw error;
  }
});

Solving the Maintenance Tax with supaguard

Instead of manually debugging connection-refused every time your CI environment changes, supaguard automates the recovery.

AI-Native RCA

Our Sanctum AI analyzes the execution trace and provides a human-readable explanation of why connection-refused occurred in github-actions.

Automatic Region Verification

If a check fails in one region, supaguard automatically retries from another to confirm if the issue is global or specific to the github-actions network.

Start guarding your apps with supaguard.
