Lately we've been using invisible reCAPTCHA, and more recently reCAPTCHA v3.
Both are hidden and don't require the user to enter a code or tick a box to confirm they are human.
So when there is an error for whatever reason, the message is likely to confuse the user (like attached).
Normally these errors would only be shown to a user if they did something to trigger googles spam detection, like filled the form to quickly or too slowly, or from an IP range thats known for spam, etc. Also during UAT it shows up a lot as the same people register over and over to test a site.
What error messages do you use or would you suggest for this situation? Something generic like "There was an error processing the form, please try again" (because in most cases, if the human user refreshes and tries again it will probably work).
Interested to know what others have done?
