I am facing a strange behaviour without any changes in setup or pipeline of the suite. Last I upgraded to latest versions 2 weeks back and it was running smooth on jenkins till 2 days back.

Some of my tests are failing at the suite setup New Browser keyword with following error:

`Suite setup failed:
TimeoutError: browserType.launch: Timeout 30000ms exceeded.

My New Browser Keyword looks like this

New Browser
... headless=${HEADLESS_MODE}
... channel=${BROWSER_CHANNEL}
... args=["--start-maximized"]

Pipeline is docker based with following additional args executed

FROM ghcr.io/marketsquare/robotframework-browser/rfbrowser-stable:19.5
USER root
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update
&& apt-get install -y locales
&& sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen
&& dpkg-reconfigure --frontend=noninteractive locales
&& update-locale LANG=en_US.UTF-8
&& npx playwright install chrome
&& npx playwright install msedge

this is happening for both channel chrome as well and msedge

Hi - Try below code for headless. I am not sure if this resolved the issue but I got a similar error.

Call Method ${chrome_options} add_argument --headless\=new

Regards, 
Maksood

Hey Maksood

Thanks for the prompt reply
Shall I try directly passing "--headless=new" in New Browser Keyword itself?

New Browser
... headless=${HEADLESS_MODE}
... channel=${BROWSER_CHANNEL}

... args=["--start-maximized", "-headless=new"]

Please suggest.
