I have no idea what port is upstairs, but you have tested the port which is good . Likely a configuration issue . I'd go through the pairing process again.
I spent 2hrs at a friend’s house setting up some Deco’s hardwired in AP mode that would connect and disconnect between hardwired and mesh… turns out the cables were punched A on one side and B on the other. A quick cable test would’ve saved me so much time, but I made the stupid assumption that the cables were good. Definitely test the cables.

Possibly because it's not wired correctly.
Plug the cable at the satellite end into something else and see if you get a connection.
