What server URL is this form being submitted to?


ODK Aggregate is no longer being updated. We recommend you use ODK Central.

As to the problem at hand, my guess is that you are using a very old phone and that phone doesn't have the root certificates that would enable it to trust the server. What version of Android are you running?
