Why does this happen?

The Opensea failed to fetch error mainly occurs when an API cannot retrieve the requested information from its database. When you see this on Opensea, it’s usually because you’re trying to create an NFT out of a file that’s too large for the backend to update the database in time. 

How to fix this?

The solutions to this problem are relatively simple. Here are a few you can try to fix the Opensea failed to fetch error. 

Wait for some time

The Opensea failed to fetch error can happen when trying to make an NFT out of a rather big file. If your internet connection is slow and the upload hasn’t gone through yet, you will see these errors. The best way to counter this is to wait for 10-15 minutes and give it another go. 

Reduce the file size

Another method you can try is to compress your file and make the file size smaller. A smaller file will upload faster and hopefully resolve the error for you. Opensea allows files up to 100MB, but that can be too much for the API to handle. You should ideally keep your files between 30-50MB.

Add unlockable content

Opensea NFT listings can also carry unlockable content for the buyer. While this isn’t the ideal solution, and it won’t make your file fully decentralised, it can work if you’re willing to provide active support for your artwork even after it’s sold.

You can upload a lower resolution version of your file and have the full resolution version as unlockable content on purchase.
