Crash "Unknown socket family when converting sockaddr to host" when joining windows 10 host

[bfhv]

When joining a lan game hosted on a windows 10 machine it crashes like this. If I am to join a game hosted by an android tablet it works correctly. Seems to affect all 1.16 versions, 1.14 shows error about outdated client instead.

Similar to this ChristopherHX/mcpelauncher-manifest#145

I will try joining on win10 edition to see if I get the same crash...

[ChristopherHX]

It just doesn't crash with my network setup on intel, even if I connect to a windows 10 edition.

Is something special with your network?
ipv6 network?
output of ip addr?

My testing environment is limited

[bfhv]

Configured for ipv4&6.

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

inet6 fe80::b26e:bfff:fed1:217b/64 scope link

When I disable ipv6 I cannot see other clients, however they can find and join me no issues.

[ChristopherHX]

Well
I get this error if I try to connect to a ipv6 ip, so I will fix it soon.

[ChristopherHX]

Is it fixed with 1.16.100 and latest flatpak now?
