Hi,

We encountered the same issue at a customer's apm. BIG-IP v16.1.2.2, Edge Client 7221.
We upgraded the firmware to v16.1.3.4 and edge client to 7240. There was no change, we had to remove the captcha.

I encountered the same issue when I tested in v17.0 lab device.

Recaptcha works on the web browsers.
When I click the "I am not a robot" checkbox on Edge Client, no requests are sending to google. The below requests are not occurring in edge client.

https://www.google.com/recaptcha/api2/userverify?k=6LcWCSwUAAAAAKW5tV5p-Dsszkr....I0Hh2

There is no problem with hcaptcha.
The difference I see between edge client and web browser for recaptcha; edge client sends a request to "https://www.google.com/pre/config.php?version=2.0" and gets a 404 response.
This request does not occur when there is no recaptcha configuration.
When using hcaptcha, "/pre/config.php" request is not sent to the hcaptcha service.
