I have created a GCP Linux instance. I am running VSCode in Windows. I have run the following commands in the VSCode Terminal:

gcloud auth login
gcloud config set project ecxxxast-377213
gcloud config set compute/zone us-central1-a

This command pops-up a new Bash window:

gcloud compute ssh --zone "us-central1-a" "instance-1" --project "ecxxxast-377213"

This command runs the Bash in the current VSCode terminal:

ssh instance-1.us-central1-a.ecxxxast-377213

FAILS: Attempting to use "Remote Explorer" extension using the following config file:

Host instance-1.us-central1-a.ecxxxast-377213
  HostName instance-1.us-central1-a.ecxxxast-377213

enter image description here

This is the log file returned:

    The error is very clear, vscode does not know how to resolve the hostname since it is private to the vpc. Connect using the public ip – Puteri Feb 21 '23 at 08:20

Like Puteri said there might be some issues with IP resolution, try to use public IP and check. The other possibilities are that you might have done some misconfiguration while configuring your gcloud project in your vscode application, like selecting some default region. Check your gcloud config using the gcloud sdk and reconfigure your gcloud environment in vscode this time without selecting any region. Hope this will solve you issue.
