Bittrance

This started happening to me too today. The issue seems a race condition since the freeze occurs sometimes on the white title screen and sometimes while navigating game selection. A similar behavior occurs both on my iPad Mini 2 and on my iPhone 7 using 1.14.1. It is worth noting that on my iPhone 7 I am not logged in to an Xbox account, so that seems not to be a requirement. Playing on my Android phone works well.

This is also an issue on multi-homed hosts (e.g. home routers) where one interface is on the Internet and one is on the local net; running a server on such a host means accepting connections from the Internet.

You may be able to work around this by running the server in a Docker container where you can use the --port directive to bind a specific address.
