In order to claim you must have a certain piece of the artist’s work. I have held that NFT in that same wallet since February and have been claiming monthly but this month is says “Sorry, there are no items for you to claim.”
I’m using chrome and MM with a ledger. I have tried refreshing the page, restarting my computer, clearing cache, etc. and I still get the error.
Checked and everything looks like you should be able to claim with 0xc07..651
I simulated your wallet and it shows you have a claim available. Can you double check you have the right wallet connected by fully disconnecting and reconnecting.
If you still think there’s something up after this, can you post a screenrecording of you reconnecting your wallet to the page (showing the Wallet popup) and pressing the claim now button
