gcloud auth login throwing error: gcloud crashed (ConnectionError): HTTPSConnectionPool(host='oauth2.googleapis.com', port=443): Max retries exceeded

Question

1. gcloud builds submit failed for me yesterday.
2. Then I tried gcloud config set project, that also failed.
3. So I thought login might have expired so tried gcloud auth login.

In all cases, it always throws following error:

ERROR: gcloud crashed (ConnectionError): HTTPSConnectionPool(host='oauth2.googleapis.com', port=443): Max retries exceeded with url: /token (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x00000198B0B26970>: Failed to establish a new connection: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond'))

If you would like to report this issue, please run the following command:
  gcloud feedback

To check gcloud for common problems, please run the following command:
  gcloud info --run-diagnostics

On running diagnostics as suggested, everything seems fine.

Answer 1

This problem is with Airtel India ISP and not Google Cloud CLI. Use a VPN, and it will work.

Answer 2

The same problem happened to me and it was a proxy issue

I followed the steps to unset the proxy

gcloud config unset proxy/type
gcloud config unset proxy/address
gcloud config unset proxy/port

Answer 3

connect to a VPN or mac users enable Private Relay(Beta) in icloud setting
