gardenctl ssh <gcp_node> fails with Cmd was unsuccessful

[dansible]

Describe the bug
gardenctl ssh <gcp_node> fails with Cmd was unsuccessful (using gardenctl/gctl-gcp cluster)

To Reproduce
Using 52235f2 with a test cluster gives:

$ go run cmd/gardenctl/main.go ssh shoot--gardenctl--gctl-gcp-gctl-gcp-z1-bb4d4-flzns

Warning:
Be aware that you are entering an untrusted environment!
Do not enter credentials or sensitive data within the ssh session that cluster owners should not have access to.

Downloaded id_rsa key
Check Public IP

(1/4) Fetching data from target shoot cluster
Cmd was unsuccessful
exit status 2

Gardenctl Version (please complete the following information):

• Version/Commit 52235f2

seems working from my side - the only thing i need to do is connecting to PHILA VPN server as shanghai vpn server can't connect to google services....

Unfortunately i'm still not able to have an ssh session succeed on GCP. Both on or off the Philiddelphia VPN, I get this:

$ go run cmd/gardenctl/main.go ssh shoot--gardenctl--gctl-gcp-gctl-gcp-z1-bb4d4-xkxp6

Warning:

exit status 2

Debug mode (-d) does not provide any more info. This is the same with the released gardenctl (v0.23.1)

Thanks @neo-liang-sap, I reinstalled my gcloud command line and was able to resolve the issue 👍
