TCP Connection not working

[PLEXATIC]

I have the following Code:
th = Thymio(host="192.168.138.1", tcp_port=52906, use_tcp=True) th.connect() print("connected")

My Thymio Simulator is running on the IP and Port I put in the code.

The Code doesn't throw an Exception, but it's stuck in th.connect(). I waited for over 10 Minutes and it didn't connect. I tried altering the IP Address to localhost which didn't help.
