kubernetes ClusterIP 10.3.240.1 <none> 443/TCP 27m
On the browser enter the external-ip value and see if it's coming as V2.0.0
Or you can do curl 104.197.10.135 that should also give you the output on the GCS cloud shell prompt!
You should get something like this
Echo Test

Hostname: echo-web-7f978f856d-rjb2j
Host ip-address(es): 10.0.1.8
Enjoy :)
