Google Cloud Platform Unable to Pull Data

[rja93]

Hi all,

I am trying to pull data from Google cloud to Splunk. After configuring google cloud credential and cloud monitoring input I am seeing the below error in logs and can't see any google cloud platform data in Splunk. Please check the below error and suggest what can be done to fix the issue.
I am running Splunk 7.3.1 on my PC and running an enterprise version.

My compute engine instance on GCP has full access to all Cloud APIs.

Any help is greatly appreciated!

I have also configured my google_cloud_global_settings.conf in my Splunk_TA_google-cloudplatform/local to:
[proxy_settings]
use_hec = 0
disabled = 0
proxy_password = ******
