Start with the message shown in TCG STATS. Most problems come from missing card information, a disconnected marketplace or a marketplace rule that needs attention.

## Check these first

1. Confirm that you are working in the correct TCG STATS location.
2. Open **Settings → Connections** and check the marketplace.
3. Open the inventory item and verify product, variation, condition and quantity.
4. Open the listing and read its latest status message.
5. Retry only after correcting the cause.

## Choose the problem
