Specifically, that gateway (and some (all?) others) needs "/ipfs/" in the URL: https://ipfs.io/ipfs/QmTqkpmbKmciQgqhUWpML7dsJ59MBEjgQd7wH85...

Took me a while to figure it out, but the docs are here: https://docs.ipfs.io/how-to/address-ipfs-on-web/

I also ran into several apparently no-longer-functional gateways in lists from just a few months ago. So yes, not the true experience.
