Teamviewer not starting up early when using a lan cable

Options

I want to connect to my device with teamviewer in the windows logon screen. I have checked the box in the options settings of teamviewer. When I use a wifi connection, I can connect to the device when in logon screen (this does confirm that it's possible to do even though I use a free license), but when I start the computer up using a Lan connection (and yes it has the internet access), team viewer says its unable to connect. When I entered my password and on the desktop screen, the device is online again on teamviewer. So there is something that is blocking me for using teamviewer within the logon screen when I have the lan cable connection.

I looked at the log files and compared the wifi log files with the lan log files and found some weird logs:

I'm not sure if the KeepAliveClient is the part that is used for starting teamviewer within logon screen, because I couldn't find anything about it on internet.

I'm out of options, so any advice is helpful.

If I need to provide more details, I can give them.
