Firewall Issues

Use this guide to troubleshoot firewall issues when trying to access Luminary Cloud or the Luminary Cloud SDK.

Updated over 2 weeks ago

If your company has restrictive firewall rules, you may have trouble accessing our app and our Python SDK. The most common symptom of this is seeing a grey screen after logging in:

Domains and Ports

Your browser or API integration must be able to reach any of Luminary’s fully qualified domain names for it to function properly.

We've found that adding https://app.luminarycloud.com and https://luminarycloud.com to your firewall's allowlist is enough to get past most types of firewall issues that prevent access to Luminary via the browser or the API and Python SDK.

If that doesn't solve the issue, try adding these additional domains to your allowlist:

Proxy Servers

If adding the above domains and ports to your firewall's allowlist is not working and you're using a proxy server, please ensure that any proxy servers deployed on your network are set to not alter SSL certificate chains for the above domains. Some browsers may implement additional security checks (certificate pinning) for well known domains.

WASM File Access

If the above steps do not resolve the issue, confirm that your network is not blocking .wasm files, as these are essential for application functionality. To verify, perform the following steps in Google Chrome:

  1. Open the Network tab in Chrome Developer Tools:

    • Go to View > Developer > Developer Tools or press F12.

    • Click the Network tab in the Developer Tools panel.

  2. Refresh the page and observe network requests to identify blocked resources (e.g., .wasm files).

If .wasm files are being blocked, ask your IT team to allow these files through the firewall.
