Hi @SUNDAY_OMACHOKO! Welcome to the ODK form. When you get a chance, please introduce yourself here!

This error generally happens when there is a failed network connection. In this case, the address of the server is wrong. You forgot a . (dot) before appspot.

Thansk @yanokwa. i will rectify the error.

Introduction has been done.
