Unable to update app: Bad authentication response: 404 Not Found

I was having this same issue. As it turns out the authentication method (ClientLogin) I was using to deploy to appengine was deprecated (I was deploying using mvn gae:deploy). Google now wants us to use their new OAuth 2.0 authentication for deploying to appengine: https://cloud.google.com/appengine/docs/deprecations/clientlogin
To fix this issue I had to update my appengine maven plugin to use the latest version so I could deploy.
I added this to my pom.xml:
<plugin>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>1.9.34</version>
</plugin>
Then I used this command to deploy (instead of mvn gae:deploy):
mvn appengine:update

I had opened multiple google accounts. So, I did close all and deployed it again. It did deploy. It was my mistake.

- Install Google Plugin for Eclipse.
- Open your project in eclipse. Once you install the plugin successed, you will see a new button of "G" on eclipse buttons bar.
- Click the "G" button and then click "Deploy to App Engine".
- Done.
