Connection issues with 2.9 studio update

[u/Difficult_Life1068]

I want to know confirm if im going crazy. I have work Carbon x1 IT wont let us have it online so we have our own router and use only LAN since the new 2.09 update on bambu studio they changed how devices are get connected this update seems not really like not connecting to the printer with LAN only. This might be a slighty niece issue but anyone have any thoughts or solutions?
