Upgrade chromedriver.

[arroyoc]

Verified that upgrading chromedriver to version 2.33 fixed this problem.

Even after the update to version 2.33 the maximize action still don't work. If I remove it, all goes well.
driver.manage().window().maximize();

@alexandrera by chance are you on linux? https://bugs.chromium.org/p/chromedriver/issues/detail?id=1901&can=1&q=maximize&sort=-id&colspec=ID%20Status%20Pri%20Owner%20Summary

[alexandrera]

No, actually I'm on Windows 10.

Updating chromedriver and selenium standalone jar fixed this issue for me.
I was using windows 7 and python.

[varuntaneja]

it worked after updating chromedriver..

[Himanshuhacks]

I was also facing the same issue. I updated my chrome driver to version 2.33 and now it is working fine

[Udhh]

For me also, it worked after updating the chrome driver.

[samlucax]

I'm using the chromedriver 2.33, and I had to remove the maximize() function to work as expected.

There are someone facing the same problem using the maximize ?

[lmtierney]

@samlucax depends, are you on linux? https://bugs.chromium.org/p/chromedriver/issues/detail?id=1901&can=1&q=maximize&sort=-id&colspec=ID%20Status%20Pri%20Owner%20Summary

[mshimer]

upgrade to chromedriver 2.33 fixed this for me. Download latest and move to node_modules/selenium-standalone/.selenium/chromedriver/

Get rid of old one.

Hi, Even I am getting the same problem for Maximize. I did upgrade the chrome version to 2.33 still getting the error. It is working fine on local machine with the upgrade but when I deploy my test on server through tfs. I am getting this error for maximize. its win 10 on server.

Hi,
I am using Windows 2012 R2 server(64-Bit) . From Jenkins i am trying to run a job where it has to open URL using Robot framework tool. In my Script I used "Maximize Browser Window" Selenium keyword. When the execution comes to this keyword it is constantly failing with "WebDriverException: Message: disconnected: unable to connect to renderer" error.
I am using 2.33.506120 Chrome Driver version and Chrome Version is "62.0.3202.94" .
Can anyone Please tell me what might be the reason and the remedy for this.

Thanks.

@ameykhopade2 are you sure that on win 10 server the latest chrome browser & driver are installed?

[ameykhopade2]

its working fine now. latest chrome browser was installed on the server but my TFS build was now deploying the new browser which was creating the problem changed the build def and its working with the upgrade to 2.33.
thanks:)

Thanks.

[sarodemallika]

options.addArguments("no-sandbox"); - solved the problem.. :)

[mvpmurali27]

options.addArguments("no-sandbox") and version 2.33 solved the issue with chrome v 62.0.3202.94 and python 2.7x

[sarodemallika]

I am using chromedriver 2.30.0.1 as 2.33 is giving some problem .

[kulavardan]

1. Upgrade chromedriver
2. Remove window size set keywords if you are using any

[Jia-ullah]

Yes it worked after updating chrome driver. I upgraded to 2.3.4 version. Thanks :)

[sreeramydk]

It worked for me after upgrading my chrome driver to 2.3.5 version. Thanks..

It causes because page took long time to load , you need add additional line to your chromedriver option. Please refer the below link for more information :
