Packer: VMWare-iso not connecting to Network

I am trying to deploy a CoreOS Image into an ESXi 6.5 Server.

The Issue i am facing is that the Machine is unable to connect to the "VM Network" on the ESXi Server.

Networkdevice says its connected if i set the following: "ethernet0.startConnected": "TRUE"

But if i look into the machines hardware configuration in the ESXi UI it says "connected: false"

As I wasn't able to find a proper documentation on the vmx_data, I manually created a coreOS machine on the Server and exported the configuration. Which leads to a ovf file. Then i converted the ovf file to a VMX Version of said machine and copied the configuration into my json. Linked as "Full Sample"

However this leads to the same behaviour as the reduced version. I provided both as I'm not sure if I'm missing something essential in either configuration.

The ESXi host is in default configuration. To minimize possible Sources of Error i have turned off the firewall of the Server is its not in productive use.

The Machine I used as a template works fine. Created by manually registering a machine on the host using the same image

And I am able to ping google from within the manually created machine. I am unable to do the same from the machine created by packer. I tried to do this by using the ESXi web interface to create a shell on the VM, while packer is waiting for the ssh connection to pop up.
