Has this ever worked, or no, this is the 1st time and it never has?
However, at one point yesterday, it was saying that it could connect but that I had the wrong passcode (I did not).
Just once or now always when you test the connection?
Are they both connected to the same network and on the same type - for example, they are both on Ethernet?
As a test, please ensure both are indeed ethernet-connected.
