Since we’ve been using ODK1 with great success, I’m now attempting to learn about ODK2 by going through online documentation.
However, when trying to use the ODK 2 Simple Demo Application (https://docs.opendatakit.org/odk2/getting-started-2-user/) using the https://opendatakit-simpledemo.appspot.com server (using Username: None (anonymous access) ) to sync the phone apps, I repeatedly get the error:
A communications error occured
Please verify your device
browser can access your server.
I know my phone can access the Internet on 3 different data/WIFI connections.
If I try to do the same with my own ODK Aggregate (v.1.6.1), I don’t get any errors. (Nothing happens because I don’t have anything on it, but no errors.)
My Samsung Note 4 is using Android 6.0.1,
Android Services 2.0.5 rev 224
ODK Tables 2.0.5 rev 224
ODK Survey 2.0.5 rev 224
OI File Manager 2.2.2
Here is a screenshot of the error:
Any ideas what is wrong?
