Post action doesn't work


I'm facing something strange
I created an app that puts data into a Google sheet.
It works perfectly if I'm connected with cellular network.
But when I'm connected to WiFi nothing goes through.
If I disable the wifi when the app is open and trying to send I get the 1103 error.
Does anyone know what is causing this?

This seems to be contradictory.... ?

What settings do you have on your device when connected to wifi?
Perhaps try a test for internet connection when app is open ?

The internet connection on the wifi works perfectly. Although I noticed some trouble when updating apps in the play store
