Recaptcha slow internet connections issues and 5 seconds abort

[armin_imsirevic]

My clients with slow internet connections have encountered issues with passing reCaptcha. The issue can be reproduced by throttling internet connection speed (for example, to 2G) and attempting to pass reCaptcha. Requests to the reCaptcha API are aborted after 5 seconds on slow connections. I have tried to find a way to override this 5-second abort, but there is no information about it in the reCaptcha documentation.

I would like to know if there is any way to increase this 5-second abort or some other way to handle slow internet connections in this case?

Reproducible on demo (https://www.google.com/recaptcha/api2/demo) by throttling download speed to 40kbits and upload speed to 10kbits.
