Selenium works when started locally, but not remotely

I'm hoping this is a simple issue to solve:

I have a dedicated machine that runs selenium with chromedriver. I can physically walk to the machine and type the following in a local terminal:

java -Dwebdriver.chrome.driver=chromedriver238 -jar selenium-server-3.11.jar

I can then go to any other machine on the network and kick off testing (in my case, codeception on jenkins) and it will sucessfully run my tests in chrome without a hitch.

However, if I try to run the above command without physically being at the selenium machine (ex, trying to ssh into the machine to run the command or making this command run as part of a supervisor process) then selenium has trouble starting the instance of chrome.

Has anyone run into this scenario before? Is there a way I can give 'interactive' access to the background script to allow it to open stuff on my screen?

I'm to getting the same scenario, when i try to start the selenium code on the machine A it works yet when i try to start selenium and run the scripts from machine B (remotely connecting to machine A using ssh [ssh test@machine-a]) chrome instance doesn't start/launch and driver is getting null.

logs :

2020-02-27 12:04:27,319 INFO [LogWritter] Exception in beforeclass chrome driver instantiation , driver is null

2020-02-27 12:04:27,493 INFO [LogWritter] Exception in getting screenshot---java.awt.AWTException: headless environment

Any help/suggestion would be great !

Because when you physically walk to the machine and run the command. the selenium can get the desktop/window interface.

When use SSH, selenium lost the desktop/window interface, selenium have to start chrome under headless model, but your code not config to run as headless model. So the conflict come out.

you need to config your code to run with headless model.
