Cant pair on the SteamDeck Connection closed Error 2

Describe the bug Every other device can pair with Moonlight, however my Steam Deck refuses to pair. I get the Pair pin pop up and after a few seconds I then get a "Connection closed (error 2)". I do not get the usual pin popup on my host machine like I normally would when a pair request is sent and also when the pin that is briefly showed is used it is refused.

Steps to reproduce Open Moonlight click to pair, the pin is displayed but after a few seconds a message "Connection closed (error 2)" is displayed
