Cypress Tests fail with TLS Error when using OWASP Zap as proxy server

[james-luther]

I'm attempting to use OWASP Zap as a proxy server to run all e2e tests through. When running all tests fail reporting the following:

We attempted to make an http request to this URL but the request failed without a response.

We received this error at the network level:

Error: Client network socket disconnected before secure TLS connection was established

Common situations why this would fail:

• you don't have internet access
• you forgot to run / boot your web server
• your web server isn't accessible
• you have weird network configuration settings on your computer

Here is my cypress info:

The ZAP proxy is working as I am able to manually reach and test the endpoints Cypress is testing. When I remove the proxy all tests complete successfully. I'm not sure where I am going wrong.

@james-luther Did you every determine the root cause for this? Running into it now and came across your post. Thanks!

[james-luther]

I did actually! I set the HTTPS proxy to the same endpoint as HTTP. I reached out to the team for ZAP and was informed they were working on this kind of use case but I never followed up after finding my solution.

@james-luther Thanks for the response! I've got those set, but still seeing it. Dang. Were / are you running in Docker?

[james-luther]

@jacobbundren I was, it was specifically running in CircleCI. The base container was ZAP and I installed everything for cypress. They both ran together

@james-luther I'm gong to give that a whirl. I've been using the Cypress base image. I'll report back. Thanks again for the insight.
