Blank page & Timed out waiting for the browser to connect. Retrying...

[mattensor]

Hey there,
I'm having a little difficulty running Cypress and am looking for some help :)

When I run npx cypress open and attempt to run the suite using electron 59 or chrome 74 I get a blank page. When I check network requests for the page the html and cypress runner loads fine but the upgrade to web socket does not respond.

When I run npx cypress run this is what I get

Timed out waiting for the browser to connect. Retrying...
Timed out waiting for the browser to connect. Retrying again...
The browser never connected. Something is wrong. The tests cannot run. Aborting...

I've tried reinstalling cypress a number of times and the Cypress tests run fine on other developers machines.

Node version v10.15.3
Npm version 6.4.1
Cypress Version 3.2.0
Mac OS Mojave 10.14.4

any suggestions or ideas would be great!

Can you try cypress v3.3.0 please? It solves a lot of proxy issues

I just upgraded to 3.3.0, still having the same issue

[jennifer-shehane]

@mattensor Sorry to hear it's not connecting.

Can you provide a reproducible example that we can run? It likely has something to do with the url you are attempting to visit during cy.visit() (can email url to [email protected] if you do not want public).

Also a screenshot of the 'blank page' on cypress open would be helpful. Can you make sure to open the devtools on screenshot to see any errors?

During cypress open - print DEBUG logs and paste here also: https://on.cypress.io/debugging#Print-DEBUG-logs

[mattensor]

Thanks so much for your help @jennifer-shehane .

I have some screenshots for you. It seems the websocket upgrade request is timing out, and it's not even getting to my actual cypress tests.

Any help you can give would be really appreciated :)

Facing the same issue.. Electron locally works fine, when trying remote from gitlab CI it cannnot connect..

[jennifer-shehane]

@tijnster I believe your issue is likely different since it is isolated to GitLab CI run. Could you open a new issue with as much information as possible?

@mattensor We've seen some similar issues in the past, which they were able to resolve through some debugging or they never provided a way to reproduce.

• Clearing app data solved it - Timed out waiting for the browser to connect. - both on headless and GUI #2017 (comment)
• Issue is hosts file - Tests from example_spec.js don't run in Chrome after newly installed cypress #680 (comment)

Can you try some of our troubleshooting techniques? Logging DEBUG logs or clearing App Data?

Are you behind a proxy? Have you configured the proxy?

[tijnster]

@jennifer-shehane Sure, will do!

When I run cypress with debug here is what I get

cypress:server:server Got CONNECT request from localhost:55871 +21s
  cypress:https-proxy Writing browserSocket connection headers { url: 'localhost:55871' } +21s
  cypress:server:server HTTPS request does not match URL: https://localhost:55871 with props: null +0ms
  cypress:https-proxy Making connection to localhost:55871 +1ms
  cypress:network:connect received error on connect, retrying { iteration: 0, delay: 0, err: { Error: connect ECONNREFUSED ::1:55871 at Object._errnoException (util.js:1024:11) at _exceptionWithHostPort (util.js:1046:20) at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1182:14) code: 'ECONNREFUSED', errno: 'ECONNREFUSED', syscall: 'connect', address: '::1', port: 55871 } } +894ms

I have cleared App data & the same problem still persists.

I got logs similar to these. The problem was that my

/etc/hosts

file did not include a line:

127.0.0.1 localhost

[mcntsh]

@mattensor did you ever get a solve for this? I'm facing the exact same issue.

[mattensor]

I needed to include 127.0.0.1 localhost in my host file
