I have a few machines that operate headless on my home network, or are in another room, and I use TeamViewer over LAN to connect to them. The reason i use LAN IP address is because i have a slow internet speed, so a regular connection out through the TeamViewer servers and back in makes it very slow. When i type the IP address in the "Enter Partner ID" field at the top of TeamViewer as i always have it no longer connects, just does nothing at all, no error pop up or anything. If i go under the "Remote Control" tab however it works, why does it no longer work in the top field? Was this intentional after an update?
