Issue with Uart

I have recently bought a cp2102 usb to uart bridge for my Rc. When I plug both of the them the green light keeps on so I assume they are connected together. But now I’m trying to connect it into mission planer but it’s not working. The Com are showing but when I try to connect it it shows to me this error :
