Turnstile API throwing invalid-input-response error code

[sdayman]

That sounds like this post, where the user was able to fix it:

Suddenly error invalid-input-response

I found the problem. In the server I was getting the remoteIp using req.get(“origin”) I checked in the docs and changed to req.get(“CF-Connecting-IP”) With this correction I was able to register. The only thing it’s that this has worked for more than a year and only today the problem pop up.
