Hi Andy,

Welcome to ODK Forum, if you have a moment, feel free to introduce yourself [here](https://forum.getodk.org/t/introduce-yourself-here/6671)

I am assuming that you have configured a self-signed SSL certificate. If that's true then ODK Collect will not work with it even if you have trusted the certificate in your Android device.

You would need a CA signed certificate for Collect to work.

Thanks,

Sadiq
