figma weave 504 gateway timeout error fix

When generating layouts or processing complex AI prompts, encountering a 504 Gateway Timeout error usually indicates that the gateway server hosting Figma Weave failed to receive a timely response from an upstream generation node. While this often points to temporary infrastructure strain on the backend, local proxy filters, browser cache issues, or regional route congestion can also trigger it.

This independent guide walks you through diagnosing whether the timeout is widespread or isolated to your current session.

Quick checks

Before attempting deeper technical fixes, verify these baseline factors:

• Check if your internet connection is stable by loading an external high-bandwidth web page.
• Ensure your browser or desktop app is not routing through an unstable corporate VPN.
• Verify whether standard canvas edits work normally, isolating the issue strictly to AI generation tasks.

1. Check for partial or regional outages

A 504 error frequently occurs during localized server overloads. Check community status hubs or our dedicated tracker to see if Figma Weave is down across specific geographic regions before changing local settings.

1. Bypass local proxy and VPN routing

Corporate firewalls and custom proxy configurations frequently terminate lingering HTTP requests before the AI generation payload finishes downloading. Disconnect from any active VPN or security proxy, restart Figma, and retry the operation.

1. Clear browser cache or desktop app storage

Stale session tokens and cached socket connections can cause the gateway to continuously reject backend responses. In the Figma Desktop App, navigate to Help > Troubleshooting > Clear Cache and Restart. If using a web browser, clear local cache for the domain and perform a hard refresh (`Ctrl + F5` or `Cmd + Shift + R`).

1. Simplify prompt scope and clear frozen queues

If the server takes too long to compute full-page responsive layouts, it may trigger an upstream timeout. Break down your request into smaller components or frames. If your canvas generation gets stuck mid-process, review our guide on resolving when Figma Weave is not generating to clear frozen render requests.

1. Switch network DNS resolvers

Sometimes regional edge routers fail to resolve backend endpoints quickly enough. Try temporarily switching your network's DNS settings to Google Public DNS (`8.8.8.8`) or Cloudflare (`1.1.1.1`), then flush your system's DNS cache.

Still stuck?

If 504 errors persist after clearing local caches and trying alternative networks, the problem is likely an unannounced backend outage or server cluster failure. Check back in 15 to 30 minutes while backend maintainers re-route traffic.
