First test the destination separately by opening the generated public link, if the code has one. If the link works but the image does not scan, inspect the QR design and printed copy.

Use clear contrast, leave space around the code, avoid stretching the image, and test at the actual printed size. Check for glare, blur, cropping, or a logo covering too much of the pattern. Try a simpler design to isolate the cause.

If the image scans but the destination fails, check the destination URL, item status, subscription, PIN prompt, and any scan limit.

For support, provide the item name, public link where appropriate, image format, printed size, device, and exact behavior. Remove private information from screenshots.
