Client is a Steam Deck using latest version of SteamOS and latest Steam stable client.
Host is a Windows 11 PC using latest Steam stable client.

When i press the green "Stream" button on a game page, it makes an attempt to connect to the host, but it quickly comes back to the game page.
That loading splash image with a collage of banners from games of your library never appears.
Anyways, the game starts on my host, and the "Stream" button becomes "Connect" button.
Pressing the "Connect" button gaves the same result as when it was "Stream".
So now i have the game running on the host, but not streaming to the client.

Weirdly enough, if I use the Steam Link app that is on the Discover store, this issue doesn't exist, and i can stream games to my Deck as usually.

Any help with this?
