Can't mirror screen to Roku TV using gnome-network-managers

As the title suggests, I'm trying to mirror my screen to a Roku TV using gnome-network-managers.

Under my Roku settings I have screen mirroring enabled. I have tried setting it to both "Always Allow" and "Never Allow." I installed gnome-network-managers from AUR and made sure all dependencies were installed.

When I run it, the Network Displays window pops up, and my TV appears under "Available Video Sinks." When I click it, the window reads "Connecting   Establishing connection to sink" and lists my TV under that. It stalls out at this point, eventually yielding two system errors: Network Management says "Connection 'Wifi P2P Peer DA:31:34:8B:68:62' Deactivated", and "p2p-dev-wlp1s0 Authorization supplicant timed out."

Here is the debug output I get when I run

G_MESSAGES_DEBUG=all gnome-network-displays

The Network Manager logs show the following at the time that this is happening:

From all of this, and the information on the gitlab page, what I'm getting is that an IP link is being established but then timing out. But, I have no idea where to go from here in terms of narrowing down why this is happening and identifying a solution.

Thanks in advance for any help!

Re: Can't mirror screen to Roku TV using gnome-network-managers

@benpeltz did you figure this out?
I have a roku tv too and while gnome-network-displays detects the tv, it neither makes a successful connection nor do I get a prompt on the tv. Also tried 'allow always' option on tv. Doesn't work
I know the issue is not with the hardware because it works on the same device with Windows.

Re: Can't mirror screen to Roku TV using gnome-network-managers

No, sadly I never did get it working. Got my Android phone connected and settled for that.
