Cannot connect from EC2

Well, we could get gamelift working fine when we run our lobby server locally.

However, when we move our server to EC2, it just doesn’t connect to the service and just hang.

We already disable all firewalls, and add custom Policy to access GameLift to our EC2.

But still it can’t connect… any pointer about what else could be wrong here?

Best,

Never mind… we had incremental Token and apparently it got reset and reuse. Had to do a random token generator.
