Had a similar issue. You have to use their browser extension: https://chrome.google.com/webstore/detail/hoppscotch-browser-extens/amknoiejhlmhancpahfcfcfhllgkpbld?hl=en https://chrome.google.com/webstore/detail/hoppscotch-browser.... Click on this extension and add the domain you want to query. Then on Hoppscotch, go to settings and click "use browser extension to send requests." I was using Altair's desktop app to handle CORS, but may switch to this set-up.
