Form Listing Failure

1. What is the problem? Be very detailed.
Trying to get blank form from Aggregate lodged with Google App Engine but getting the following;

I am wondering if this has to do with Java certification
2. What app or server are you using and on what device and operating system? Include version numbers.
I am using Aggregate server lodged with Google Cloud App Engine
I'm using SAMSUNG Galaxy Note 10.1 to request Blank Form
3. What you have you tried to fix the problem?
I have built the XlsForm data collection form and tried on Enketo
I have installed ODK Collect v1.15.1 on the Samsung android tablet
I have created the project in Google Cloud account and lodged the Aggregate server in the App Engine.
I have also sumbmited the XMLForm to the Aggregate
4. What steps can we take to reproduce the problem?

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.

Make sure your Android device has the correct time and date. Your secure HTTPS/SSL connection requires it.

Thank you for this. Curiously that's what I realised upon giving a closer look. :slightly_smiling_face:
