I am trying to submit data to an ic2cloud server, using test code,.. However, my efforts are failing with various errors.

I have tried more variants than I care/can list but none successfully submit data to the cloud,. is anyone able to spread some light on the error of my ways,...
Are there any things I can change to improve the error reporting,.. as I am at a loss..
Many tx
