Google App Engine deployment debug "Error Response: [4] Timed out waiting for the app infrastructure to become healthy"

Question

In short: We have web app running at Google App Engine Nodejs runtime, flex environment. Starting 5 days ago all our deployments started to fail with the reason:

ERROR: (gcloud.app.deploy) Error Response: [4] Timed out waiting for the app infrastructure to become healthy.

Full error stack trace:

Before that (3 weeks ago) deploys began to be really slow (5-20 minutes).

Info about operation provided by command:

gcloud beta app operations describe OPERATION_ID

gives this:

done: true
error:
  code: 4

Any ideas how to get more info about the operation and what actions are performed?

Best,

At the moment of writing I haven't found the way to get more verbose error messages during Google App Engine deployment from CLI at Ubuntu rather than passing verbosity option gcloud app deploy --verbosity=debug or getting more info about the operation with gcloud beta app operations describe OPERATION_ID.

But they found the cause of the problem: The reason for the Compute Engine VMs never becoming healthy is because your 'In-use IP addresses' quota [1] in the region of your App Engine Flexible application has reached its limit. More here - https://issuetracker.google.com/issues/73583699. And promised to provide better error messages with the next update of the CLI
