any update guys on this ??

I have the same problem on Android devices. All browsers and also iPhone works like a charm, no disconnects. But any Android device disconnects every single time right at the start, despite the call being exactly the same as for all other browsers.

I would highly appreciate any update on this issue.

Hi @guptaakhil, if you use localhost as a testing hostname, try to use 127.0.0.1 or your Network IP, as suggested in this article. Also, try to use ports from this list for testing. You can specify it usng the ports.

@Timywitt, I've reproduced the problem with some Android browsers (Google Pixel, Samsung Galaxy S8) . I'm investigating the problem right now. However, Google Nexus 6 works for me, have you tried to run it?

[timon-witt]

Google Nexus 6 works for me as well. Even though this is not the solution, thank you very much for finding this out :)

[timon-witt]

As far as I can tell, these Android devices are the only ones that work:

• Samsung Galaxy S6, 5.0
• Google Nexus 6, 6.0
• Samsung Galaxy Note 4, 6.0

@Timywitt, I've found the reason of the problem: DevExpress/testcafe#2318 and I'm working on the fix now.

[Automation-Geek]

For Samsung devices the node version 6 will not work, it's work fine for Node 4 and v8. I am not sure problem will get resolve because the testcafe browserstack plugin comptable with Node version 6 only.

@Timywitt @AndreyBelym : this solution is not working for me , Browser becom unresponsive while we running parallel run in ff and chrome in browser Stack. kindly help me to do so.

I'm facing this issue on Chrome 53.0.2785 / Windows 10.0.0
testcafe version v0.22.0
nodejs version v10.13.0

ERROR The Chrome 53.0.2785 / Windows 10.0.0 (https://automate.browserstack.com/builds/00ee90c744f036dcffece113e5c2ce6bb72c4531/sessions/5a45c0cf6a6b11b8826c3a3e9ca410d2c5db183f) browser disconnected. This problem may appear when a browser hangs or is closed, or due to network issues.

I ran the same test case on - Chrome 71.0.3578 / Mac OS X 10.13.6 and everything is working good.

Hello
I am facing the same issue on Chrome / Mac. The test was running properly until I click on one link that redirect the browser to another page and after a long wait, I got the error:
ERROR The Chrome 73.0.3683 / Mac OS X 10.13.6 browser disconnected. This problem may appear when a browser hangs or is closed, or due to network issues.

I can assure that there is no network issue in this case, it's something to do with the way the controller manage the driver.

@Esteban26, TestCafe doesn't support Chrome versions below Chrome 59,

@adaher15, please try to reproduce the issue on a local machine without BrowserStack, submit a new bug report to the TestCafe repository and provide an example: New Issue: Bug report.

May be same as DevExpress/testcafe#2480
