Steam Datagram Relay Error

Hi, when I use the steam_api64.dll in Elden Ring with the mod SeamlessCoop 1.79 I get this error "Steam Datagram Relay Error k_ESteamNetworking Availability Unknown" when I try to open the world for coop

Maybe the emulator is not returning a proper Relay Network status ?
