Most LegoFinder identifications complete in 5–15 seconds. If yours is taking noticeably longer, here's what's likely happening and what to do.
Common causes
- Slow upload connection. The image needs to reach our servers before identification starts. On a weak cellular signal a multi-megabyte photo can take 20–30 seconds just to upload.
- Server load. Identification depends on a third-party AI vision model. During peak traffic, that backend can take longer to respond.
- Very large source image. The site compresses photos before upload, but a 50-megapixel original from a recent phone still takes longer to process than a smaller image.
- Browser tab in background. Some browsers throttle background tabs, which can slow or stall the upload progress indicator.
What to do
- Wait at least 30 seconds. Most "stuck" identifications complete on their own within that window.
- Check your connection. If on cellular, switch to Wi-Fi if available.
- Keep the tab in focus. Don't switch to other tabs or apps during upload — this is the most common cause of stalls on mobile browsers.
- Refresh and retry with a smaller photo. Most phones have a "small" or "medium" share-size option. Use that instead of full-resolution.
- Try a different browser. Privacy-heavy browsers and aggressive ad blockers can interfere with the upload.
If it consistently fails
If multiple uploads from the same device repeatedly fail, send us a message via the contact form with details: browser, device, photo size. We use these reports to improve the upload pipeline.
