Undoing a redirect loop

I was trying to redirect my landing page, and ended up sending my posts into a redirect loop. I uploaded a new redirects.yaml. It didn’t work, and I got stuck in a redirect loop:

I tried:

302:
    /: /welcome-to-streamduo

When I go to “https://streamduo.ghost.io” I end up at:

https://streamduo.ghost.io/test-post/welcome-to-streamduo/welcome-to-streamduo/welcome-to-streamduo/

and so on…

I tried to fix by resetting the redirects.yaml to be empty:

301:
302:

I un-cached chrome, and tried it in incognito and guest, still seeing the issue.

Any ideas on how I can address? Any options to wipe the redirects clean?

Thanks.
