IFS Cloud middletier installation kubernetes connection error

Hi,

we are trying to install IFS Cloud as a remote deployment option.

We have 2 servers Ubuntu 20.04 and Windows Server 2019. The Windows server has a oracle database installed with a dump from customer’s APPS8 environment, and all the artifacts downloaded from Lifecycle experience. 

When running the main.ps1 script, we are running into some connection errors for the Ubuntu server:

1. If we leave the ManagementServerIP in main_config.json empty, the main.ps1 returns following errors during execution:
   •  Error: Kubernetes cluster unreachable: Get "https://<server_ip>:16443/version?timeout=32s": dial tcp <server_ip>:16443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
2. If we give the Windows Server IP in the main_config.json, the main.ps1 execution finished without error, but afterwards all kubectl commands return the following error (and the IFS Cloud installer.cmd returns the same error):
   • > kubectl version
     Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.7", GitCommit:"132a687512d7fb058d0f5890f07d4121b3f0a2e2", GitTreeState:"clean", BuildDate:"2021-05-12T12:40:09Z", GoVersion:"go1.15.12", Compiler:"gc", Platform:"windows/amd64"}
     Unable to connect to the server: dial tcp [::1]:8080: connectex: No connection could be made because the target machine actively refused it.
