ERC721 Minted NFT not showing on Opensea.io testnet - blockchain

Question

I run my code on rinkeby etherscan network and it works perfectly. But the image and descriptions are not showing on opensea testnet. I run the /validate/ url it shows Valid: "false".
Here is what I found when I force update on opensea, https://testnets-api.opensea.io/api/v1/asset/0x668D179B933af761e4732B084290D32B3235C22b/0/?force_update=true
Here is my code:

ipfs://QmaoMZ19zhpC6T4id6jdBP1Qz5dQSmRZMkQZU7Zt8hyFNQ/

Answer 1

as you can see in the right up corner there is a "reload" button, you need to click it to reload the ipfs on opensea

Answer 2

I had the same problem. Turned out that I wasn't uploading the images to ipfs correctly because it was visible only to me on my machine. So try to see if the ipfs metadata are correctly formated and are accesible from different devices.
Also you shouldn't just paste your entire contract in. Tt is really hard to answer your question then. Just write out the important sections of the code.
