In longer sessions (more than 1 hour) moonlight starts to send the "SLOW CONNECTION, LOWER YOUR BITRATE" why so?

it is a problem with my host? because my network is almost perfect, I mean Wifi 6e and im playing with the router in my head (imagine tho) while the router is connected to the pc via ethernet.

my host pc has a r5 3600 and a rx 6600xt

and my client is a steam deck oled.
