Connection issue using cellular network data

Game works fine on wifi network, but won’t connect to game servers on cellular data. Even using Google account login. Always says servers are offline.

Any thoughts or advice or fixes!

Same problem. I’m on TMobile us using a lg v60

Finally figured it out. Celtic heroes has the same problem btw. The problem is, it does not support IPV6 properly. I created a new APN, that was identical to the default, except it specified IPV4. I am a bit perturbed that they don’t support IPV6 in 2021. Seriously?!

You can also set it for IPV4/IPV6 and it works.
