Unable to connect to the IS hosted in Google Cloud from Designer

Hi All,
I have installed the Integration Server (10.3) into Google Cloud. When i am trying to launch the admin page of IS, i am able to launch it.
However, when i am trying to connect through Designer, it is not resolving the IP address itself.
Could anyone help me here. Thanks.

Screenshot?

Where is the designer installed and being launched?

Also, can you try different settings on General>>Network Connections from Windows-Perspective if that helps.

Hi Mahesh,
Designer is installed in my local machine.
I tried changed the network settings to Direct / Manual; but, no luck.
