Getting 401 when trying to create claim page

Hey all!

I recently deployed my ERC1155 contract to mainnet, im now trying to create a claim page.

I am able to select my newly created contract, but when I click next, I am met with a 401 unauthorized error & the ui says “Something went wrong Try again?”

I’m connected to manifold with the address that created the contract, not sure why i’d be unauthorized.

Anyone run into something like this?
