Getting this just now too. Since ypang’s message was 11 mins ago (and I’m guessing we both got to this very old thread via Google), it seems like there must be some sort of outage happening right now.
The error is accompanied by a warning in the console: “[Cloudflare Turnstile] Ignored message from wrong origin: https://foo.com” where IIUC, foo.com is actually the right origin - i.e. the origin of the page on which turnstile is embedded.
Yeah I think it was for a subset of users, but it seems to be recovering now (at least for me). Still getting user reports rolling in though, so it could be somewhat intermittent/random.
This is still very much an active issue. It seems Safari is working fine, and Firefox is most of the time. But Chromium based browsers are having issues. For example I can’t even get to this forum using Brave because the turnstile doesn’t load.
Edit: and right after I posted that, it seems the issues have been solved and the service is back to normal
