Unable to deploy my app as I started getting below error since today morning. I have tried gcloud info --run-diagnostics and gcloud components reinstall without much help.

I tried to deploy it using the old Google App Engine Launcher for Windows but faced the same error. Earlier it worked till yesterday night (IST) using gcloud. Please help!

I am on latest gcloud sdk and have updated all its components. I use Win10. I tried rebooting my laptop as well. 

C:\gaurav\coding\python\myapp\myapp\dist>gcloud app deploy --project=myproject --version 1 --verbosity=info ./app.yaml

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

Do you have a network proxy you would like to set in gcloud (Y/n)?  n

Although gcloud info --run-diagnostics complains that the three URLs are not reachable. I am able to open them from web browser.

I found that when using Fiddler (for viewing network traffic) and have decrypting https traffic enabled, then I received the SSLHandshakeError.

Stopping the tool (or choosing not to decrypt https traffic) and then running the gcloud resulted in success.

According to the comments, also a problem with other web debugging proxies such as Charles.

Upgrading to Python 2.7.9 on MacOS High Sierra solved the issue for me.

I had this issue upon install of the google cloud SDK on MacOS Mojave. I am not behind a corporate proxy, and all the answers on the web seemed to indicate that this was the issue. I noticed in the install.sh script that it takes an environment variable CLOUDSDK_PYTHON for the python executable. So, I fixed this by exporting the path to my python 3 executable.

In my case: export CLOUDSDK_PYTHON=/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6

The install worked as expected after this.

I had the same issue, downloaded the root/intermediate cert from one of the google url you get when you run the command: gcloud info --run-diagnostics and append to the cacerts.txt file that is being used. In my case it was the following one: google-cloud-sdk/lib/third_party/httplib2/python2/httplib2/cacerts.txt

For me it was a conflict in the python versions. gcloud was calling a different version. The solution was to set CLOUDSDK_PYTHON to point to the correct python (python2 in this case).

I tried to deploy gcloud and I was getting this error. Here is how I fixed it:

  1. Access to Google cloud using Firefox

  2. Download certificate. pem file and chain file

  3. Append them on cert.pem located at: C:\Program Files\google-cloud-sdk\lib\third_party\certifi\cert.pem (using this you are creating custom CA cert file based on your proxy)

  4. Update cert file as mentioned here: https://cloud.google.com/sdk/gcloud/reference/config/set (Absolute path to a custom CA cert file.)

Make sure you have cert.pem at the end of path.

I fixed the problem by installing gcloud from apt-get. The guide is at this link
