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/](https://docs.opendatakit.org/odk2/getting-started-2-user/)) using the [https://opendatakit-simpledemo.appspot.com](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  
Network Error.  
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?

@Greg_Pommen, sorry you are having issues but thanks for posting the question.

I just synchronized with the server and verified it it should be working. I am guessing it might be a user issue, therefore, I would go to settings and click on “Reset Configuration” (red arrow) to reset all the server configuration. Then I would got to the “Server Settings” (blue arrow) screen and make sure you login using anonymous.

Let me know if that does not solve the problem for you.

@W_Brunette Thank you very much, it’s working now!

Earlier I had it working then it stopped being able to sync so I thought maybe the problem was on your end. A good learning experience for me!
