Necropost, but ...
If nothing else works, try disabling mobile data when you want to use WiFi. An app (improperly written) to "choose" the "active" connection more than once, when there are two connections, can connect using one, then respond using the other - and since it hasn't connected using that second connection, the server ignores it. (You can't talk to a server until you've connected to it - those are two separate actions - and the IP addresses of your WiFi connection and your mobile data connections have to be different. [You can't be using the same "router" for WiFi that the carrier is using to get to the internet, and it's the connection that the router makes that sets the IP address that's sent to the server.])
