[stable/prometheus] Installation fails with: Release "metrics" failed: context canceled

[svparijs]

Describe the bug
A clear and concise description of what the bug is.

Version of Helm and Kubernetes:
Kubernetes 1.13.10
Helm v2.14.3

Which chart:
Prometheus-operator 6.11.0

What happened:
While installing a clean prometheus-operator stack the response returns a: Release "metrics" failed: context canceled.

helm upgrade --install metrics stable/prometheus-operator -f values.yaml --namespace monitoring --debug
[debug] Created tunnel using local port: '49691'

[debug] SERVER: "127.0.0.1:49691"

[debug] Fetched stable/prometheus-operator to /Users/spa11916/.helm/cache/archive/prometheus-operator-6.11.0.tgz

Release "metrics" does not exist. Installing it now.
[debug] CHART PATH: /Users/spa11916/.helm/cache/archive/prometheus-operator-6.11.0.tgz

Error: release metrics failed: rpc error: code = Canceled desc = grpc: the client connection is closing

When looking at the configuration parts of the stack work.
Grafana is working as expected.
Alertmanager is working as expected.
Prometheus shows a few errors:

Which shows the broken state.
metrics 1 Fri Sep 27 16:54:20 2019 FAILED prometheus-operator-6.11.0 0.32.0 monitoring

What you expected to happen:
A completely working prometheus-operator stack, as it previously did.

How to reproduce it (as minimally and precisely as possible):

helm secrets upgrade metrics --install stable/prometheus-operator -f values.yaml -f secrets.yaml --namespace monitoring

Anything else we need to know:

It previously worked. Currently it fails on Kubernetes version 1.12.8 as wel.

Its seems to be related to this: #6130 and #15977

The suggestion of helm/helm#6130 (comment) helped.
Incombination with clearing your helm cache.
