Cannot connect to server using Android phone hotspot

I have a Motorola Stylus G and have my PC currently connected via wireless hotspot. I tried this both USB and wireless. I can login through the launcher put in password and even launch game. But when II try to connect to the game, it sits there for a while then complains about cannot connect please check network. Any ideas?

It could be that your cell carrier is filtering or blocking certain ports that happen to be required for the game client to connect.
If possible, attempt the same configuration with either another's hotspot, using a different cell carrier, or use a VPN app.
