testcafe stuck with error "upstream connect error or disconnect/reset before headers"

[gal432]

What is your Test Scenario?

navigate to site

What is the Current behavior?

before the test even starts, I'm getting "upstream connect error or disconnect/reset before headers" in the browser. no indicative error on the process. the test itself will stuck forever

What is the Expected behavior?

No error / timeout in case of failure in setup the browser & exit failure

Steps to Reproduce:

Statistic bug. should be run in loops to make this reproduce. I see it more often when I run the tests in CI (after I saw the tests got stucked in my CI server, I tunneled & connected to the chromium debugging port and saw this message)

Debug logs didn't help since its even before the tests starts. in the fixture level and I don't get any logs about it when DEBUG=*

Your Environment details:

• testcafe version: 1.1.0
• node.js version:10.14.2
• command-line arguments: chromium:headless --no-sandbox /tests/e2e/tests/Tests/CITests/ --dev -r spec,xunit:/tests/e2e/tests/ui-test-results.xml

We didn't face such an issue and it does not look related to TestCafe. I think it's somehow related to your project/environment. So, please provide us with a working example which demonstrates the issue.

I'm sad to say that you right. its indeed coming from my env. I don't sure why (envoy with multiple proxies).
but for some reason when the testcafe gets this 503 page everything is stuck. No matter where I put a code to patch this problem (before / after in fixture, in the test itself), it will stuck the test process forever. any idea how I can patch this for now?

Since the issue can be related to DevExpress/testcafe-hammerhead#1961 as you mentioned, I think it's better to wait for the fix. So I'll close this issue as duplicate. If the fix of DevExpress/testcafe-hammerhead#1961 does not help, feel free to open a new issue with an example providing detailed information.
