Js.ipfs.tech is not adding data to IPFS

I tried to use https://js.ipfs.tech/ as an example how to add data to IPFS, as it has built-in examples. I tried to add a new string to IPFS using Google Chrome Version 116.0.5845.110. I’ve got cid: QmYKM5ucJ6Eo6SHw9n523GX4VajdeNbNqFEqSQMrrm8T9t
But it’s not reachable via: https://ipfs.io/ipfs/QmYKM5ucJ6Eo6SHw9n523GX4VajdeNbNqFEqSQMrrm8T9t
