After a lot of tests and modification in the firewall, I found the problem. It was due to outdated firewall settings (probably created during the first tests). I had tested the snaps on a real ctrlx core and initially encountered the same problem, but was able to solve this in the firewall through appropriate settings, as discussed at yesterday's appointment. After taking a closer look at the firewall on my computer locally, I noticed that there were still outdated settings. After I deleted the old settings and adjusted the new ones according to the working example, the TCP server on the host device and the client on the ctrlX core (virtual) worked without problems. If someone encounters same or similar problems, check your firewall settings. The following settings worked for me: Create an firewall inbound rule and change the protocol type (under protocols and ports) to TCP, set Local port to 13001 (or the one of your TCP server port) and leave remote port with all ports. Set the Remote IP Address (under Scope) to the IP Address of the ctrlx core (virtual) and specify the profiles (under Advanced) to private and public.
