Ok, changed from https://blog.staging.begin.com/posts/2022-01-27-the-boring-t.... Thanks!

I'm years out of date on this stuff, but I note the staging URL has found its way into Google as well, you might be able to fix that up by adjusting the <link rel="canonical" href="https://blog.staging.begin.com/..." /> to point to the authoritative URL even when the page is on the staging server.

Whelp, I'm an idiot for copying the wrong url. I don't seem to be able to edit the url, only the title.
