Cypress run won’t finish, stuck while making connection to Chrome #6540

filiphric · 2020-02-24T08:26:25Z

Current behavior:

I’m getting error: Cypress failed to make a connection to the Chrome DevTools Protocol after retrying during my tests. Usually happens during one of last tests (probably the last). I have multiple Cypress projects, happens on all of them. Tests are running in parallel, on Chrome.

Test code to reproduce

Issue happens quite randomly, I’m sorry, but I cannot really give a reproducible example, since this happens in CI only. Sending screenshots.

Versions

Cypress 4.0.2
CI: Bitbucket Pipelines
Image: cypress/browsers:node13.6.0-chrome80-ff72

Oof, yeah, these are difficult to track down.

@flotwig will cases like this get any benefit from #6532 or is this a whole new case again?

@filiphric Can you also try running with DEBUG=cypress:*? Thanks!

Let me know if DEBUG is needed as well and I can provide. FYI this problem only happens when running chrome. Headless works fine. I had this problem since Cypress 3.8 or so after upgrading to 4.1 issue still persists. It working before 3.8 as far as I recall

This issue is the follow-up for #6053 and its fix #6133 (cc @bahmutov)

happened for me as well, here's the build: https://github.com/sweetalert2/sweetalert2/commit/7d31830a6f7a9757e6a9efff56087f8501cd0e84/checks?check_suite_id=504036788

@tipsey same config . how to fix it ?

I think the problem on Ubuntu 19 is Chromium is installed via SNAP process. Cypress works on Electron and Firefox(Beta) but I don't want to try a Deb install on Ubuntu because it may break future Chromium releases. I found a Link to do this but don't want to toast my Ubunut: https://shevchuk.co/notes/2019/12/13/install-chromium-on-ubuntu-1910-from-debian-instead-of-snap

lonewarrior556 · 2020-04-08T17:57:03Z

I have the same problem when I do cypress open

:~$ lsb_release -d
Description:	Ubuntu 18.04.3 LTS

:~$ chromium --version
Chromium 80.0.3987.163 snap

:~$ which chromium
/snap/bin/chromium

what's interesting is the tests run fine doing cypress run --headed

79it · 2020-04-20T21:16:17Z

I've had this problem with Chrome too and after a bit of investigation I'm wondering if it has something to do with a change in Chrome itself. I've had this or similar issues definitely on Chrome 80 and 81 and different versions of Cypress with the latest 4.4.1 still an issue.

When Cypress opens Chrome it does so with a large number of parameters. One of those parameters is proxy-bypass-list

Using a simplified version, when Chrome is opened like this it fails:
chrome.exe "about:blank" --enable-automation --safebrowsing-disable-auto-update --test-type --proxy-bypass-list=<-loopback>

However, if the loopback value is quoted then Chrome starts quite happily:
chrome.exe "about:blank" --enable-automation --safebrowsing-disable-auto-update --test-type --proxy-bypass-list="<-loopback>"

Is there a simple workaround by setting the proxy bypass list?

leorigon · 2020-04-22T12:07:51Z

I tested the 4.2.0 version and the error does not occur anymore. So, like @79it said, I think that problem is related to Chrome.

Editing, the error happened again in the old Cypress version. :(

jennifer-shehane · 2020-05-06T05:05:32Z

@79it You can modify the launch args sent to Chrome by following the instructions here: https://on.cypress.io/browser-launch-api#Modify-browser-launch-arguments

I've reviewed the comments/logs here and have not found many commonalities between the environments across people reporting this problem. A couple of things that are common:

All running in Chrome headless
Reported in Cypress versions 4+
Error appears after running a large number of spec files?

I haven't fully verified the 3rd assertion, but from the few logs provided, they all indicated that the error occurred after a large number of spec files ran (38+).

Some questions:

Please if you can answer the questions below if you're experiencing this issue.

How many spec files run on a single machine until this error occurs?
How much time does cypress run on the single machine until this error occurs?
Has anyone ever seen this error on the first specfile launch?

I guess my theory is that this may be related to longer runs or runs that connect to the CDP several times over several spec files.

Also, tracking these debug logs specifically may be helpful in seeing if any leftover processes haven't existed properly. DEBUG=cypress:*,cypress-verbose:server:util:process_profiler

filiphric · 2020-05-07T08:27:35Z

Hey @jennifer-shehane thank you for taking a look into it. I have been experiencing this lot less recently, but I can’t put my finger down on what might have caused this.

to answer your questions:

yes, our runs usually have around 15 specs on each machine, 10 machines in total
each machine runs for about 8 to 10 minutes
no, I haven’t seen this on first spec ever. it was always on the last test of very last spec on very last machine

I’ll make sure to run with a debug if it might happen in close future

tipsey · 2020-05-07T15:45:27Z

@tipsey same config . how to fix it ?

Okay it's working now with Cyoress 4.5.0 and Chromium 81.0.4044.138. Just running the spec files that came with a typical Cypress Install.

haikyuu · 2020-05-14T10:07:58Z

I have found a workaround that worked in my Mac.

I run cypress through the API:

const cypress = require("cypress");
const path = require("path");
const configFile = path.resolve("cypress.json");

I face a similar issue running my tests in browser edge 83. It is hard to reproduce the issue, since it happens quite randomly. Like mentioned above, usually one of the last tests fails. When I'm running my tests in egde in mode headed, all tests running fine.

Current Setup:

Windows 10
Cypress Version 4.7.0
Browser Edge 83

I'm running my tests local with the command: npx cypress run --browser edge --headless

I get the following error:

Browser launch arguments:

I assume that this problem is a copy of #7450. I solved my problem by adding the following workaround provided by @stevejefferies.

Should have added to my comment above, for those looking for a potential workaround adding the disable-gpu flag on browser launch (plugins/index.js) seems stable for me at least locally:
Cypress 4+:
module.exports = (on, config) => {
  on('before:browser:launch', (browser, launchOptions) => {
    if (browser.name === 'chrome' && browser.isHeadless) {
      launchOptions.args.push('--disable-gpu');
      return launchOptions
    }
  });
}
Or before Cypress 4:
module.exports = (on, config) => {
  on('before:browser:launch', (browser, args) => {
    if (browser.name === 'chrome' && browser.isHeadless) {
      args.push(
        '--disable-gpu'
      );
      return args;
    }
  });
}

To run all test in edge without problems, you have to extend the if condition by adding the following:

browser.name === 'edge'

Now, tests are running fine in chrome as well as in egde using headless mode.

@simisimon that fixed worked for me. Thank you! :)

@simisimon that fixed worked for me. Thank you! :)

Me too! Thanks! :D

mikila85 · 2020-07-27T12:40:37Z

@simisimon !!! now we can finally run in chrome! every test file now runs 10-20 seconds faster THX 👍 🥇

paulbrittain · 2020-08-27T12:39:08Z

@simisimon That doesn't work for me, unfortunately

d0utone · 2020-09-01T08:21:38Z

I was missing the line

127.0.0.1 localhost
in my /etc/hosts file. Afterwards it worked perfectly!

This was the fix for me! Thank you!

bahmutov · 2020-09-03T13:33:13Z

@flotwig why would 127.0.0.1 localhost be important for some situations?

this solve my problem too, very much Thanks to you!

flotwig · 2020-09-29T13:20:21Z

why would 127.0.0.1 localhost be important for some situations?

@bahmutov not sure, as of 3.8.1 we explicitly connect to 127.0.0.1 to avoid this exact situation:

cypress/packages/server/lib/browsers/protocol.ts

Lines 88 to 96 in 57f5f9a

    
           const connectOpts = { 
        
             host: '127.0.0.1', 
        
             port, 
        
             getDelayMsForRetry: (i) => { 
        
               retryIndex = i 
        
               return _getDelayMsForRetry(i) 
        
             }, 
        
           }

@flotwig @bahmutov
hi, I'm starting to facing this issue again while execute with "-b chrome --headless"
previously, that fix worked for me :

module.exports = (on, config) => {
on('before:browser:launch', (browser, launchOptions) => {
if (browser.name === 'chrome' && browser.isHeadless) {
launchOptions.args.push('--disable-gpu');
return launchOptions
}
});
}

now I'm getting the same error

"Cypress failed to make a connection to the Chrome DevTools Protocol after retrying for 50 seconds.
This usually indicates there was a problem opening the Chrome browser.
The CDP port requested was 52419.
Error details: Error: could not find CRI target"

also added 127.0.0.1 localhost - not helped(also tried to add my test domains to localhost file)

CYPRESS NOT BEING ABLE TO CONNECT TO CHROME 86

Hi, I am facing the same issue of Cypress not being able to connect to Chrome. If I try to run my tests using Firefox Beta or Electron, it works. What's the problem with Chrome?

I have added the following code, but the problem persists. I mention the fact that everything worked fine until yesterday.
module.exports = (on, config) => {
on('before:browser:launch', (browser, launchOptions) => {
if (browser.name === 'chrome' && browser.isHeadless) {
launchOptions.args.push('--disable-gpu');
return launchOptions
}
});
}

krapstuke · 2020-11-10T09:23:47Z

Same with me.. tests doesn't not start to run on Windows 10, Chrome Version 86.0.4240.183 (Official Build) (64-bit). With Firefox everything works

denispalii · 2020-12-04T07:26:52Z

Hi,
any news on this, please?

DogaruRaluca · 2020-12-04T11:34:43Z

Well, for me it just started to work magically without changing anything. During the period of time when cypress was not working with Chrome I have used Brave and everything was fine.

krapstuke · 2020-12-04T12:03:11Z

Still doesn't work Pagarbiai, Asta Leonavičienė

Hi,

Any news on this issue?

Previously this fix seemed to fix the issue for us but it stopped working again.
module.exports = (on, config) => {
on('before:browser:launch', (browser, launchOptions) => {
if (browser.name === 'chrome' && browser.isHeadless) {
launchOptions.args.push('--disable-gpu');
return launchOptions
}
});
}

We keep getting this error:
"Cypress failed to make a connection to the Chrome DevTools Protocol after retrying for 50 seconds.
This usually indicates there was a problem opening the Chrome browser.
The CDP port requested was 58032.
Error details:
Error: could not find CRI target"

pav-elis · 2020-12-29T21:26:56Z

Also facing the same problem and at this point I have a question: as long as this happens on headless chrome, and in fact CI/CD pipelines usually use headless chrome runs, could they also fail due to this error?
P.S.: we are using CircleCI, maybe that helps answering my question.

danmoez · 2020-12-30T20:14:58Z

Facing the same - upgrading to using the 6.2.0 image seemed to fix the issue temporarily but facing the issue again.

cypress-bot · 2021-01-19T19:34:21Z

The code for this is done in cypress-io/cypress#14348, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

Released in 6.3.0.
