Linux client crashes when running Steam Remote Play over the Internet

[Alexithymia]

Hi all,

On Arch, Fedora, and Ubuntu: streaming a game over a VPN or the Internet causes the client to hard freeze and then crash.

Steps:
1. Enable remote play on host.
2. Login to steam client on client.
3. Be connected to another network and then VPN (or not, I port forwarded the necessary ports so it was accessible on the Internet).
4. See that the machine is ready for play.
5. Stream a game.

Results:
After connection, it locks up and I have to kill the client using pkill or kill -9.

Expected:
I can stream my games just fine.

bump; Same thing happening here with:
Host-OS and Client-OS: KDE Neon (Ubuntu 18.04)

Edit:
Is it possible this is just due to firewall settings? I'm using gufw at the client side; Disabling it or opening port 27036 (which, according to remote_connections.txt, is used) seems to fix the problem. In this case, I'd still expect the Steam Client to at least show some kind of error when failing to connect through a firewall, yet it just freezes.

I've been able to fix this when I'm streaming on the same network, but it still crashes when doing it via the Internet.
