Whitelisting IP Addresses for UI-licious Testing (reCAPTCHA & Firewall Access) ​

INFO

This guide applies only to UI-licious cloud customers.
If you are using a self-hosted installation of UI-licious, please contact your system administrator.

If you are using UI-licious for cross-browser testing, you may need to whitelist our IP addresses to ensure that test browsers can access your application.

This is commonly required when your application is protected by:

  • firewalls or IP allowlists
  • reCAPTCHA or bot-detection systems
  • two-factor authentication (2FA)
  • analytics or security rules that restrict traffic by source IP

Below is the list of static outbound IP addresses used by the UI-licious Cloud testing grid:

104.248.143.86
104.248.58.222
138.68.10.120
139.59.87.137
142.93.136.179
142.93.39.99
149.129.253.194
158.140.130.227
159.203.60.250
159.65.9.218
165.227.87.229
167.99.202.76
206.189.113.202
47.244.249.38
132.147.79.54
188.166.148.123

Troubleshooting: 502 Bad Gateway Errors ​

If you encounter 502 Bad Gateway errors when a test browser attempts to navigate to your application, it usually indicates that the application is not reachable due to network or firewall restrictions.

To troubleshoot:

  1. Check network access rules
    If your application is behind a firewall or IP allowlist, ensure the IP addresses above are whitelisted.

  2. Verify public accessibility
    If your application is not behind a firewall, confirm that it is publicly accessible from the internet.

If the issue persists after whitelisting the IP addresses, or if your application should already be publicly accessible, please contact our support team for assistance.

Handling reCAPTCHA and Bot Protection ​

If your application uses reCAPTCHA or other bot-protection mechanisms, we strongly recommend disabling them in test or staging environments where possible.

For production-like environments where reCAPTCHA cannot be disabled, whitelisting the UI-licious Cloud IP addresses is the recommended approach, instead of attempting to automate or interact with the reCAPTCHA challenge.

Shopify ​

Platforms like Shopify enforce bot protection on checkout flows, which cannot be disabled by the merchant. If you need to test order placement on Shopify, we recommend using the Shopify Bogus Gateway in your test environment.
