I have a problem with running a test in headless mode. I wrote my test cases in two different (web shop and portal). Likewise, I am using Headless, my test works when headless is true in web-shop, but they don't work when headless is true in portal test cases.
org.openqa.selenium.ElementClickInterceptedException: element click intercepted: Element is not clickable at point (480, 483). Other element would receive the click: ...

You did not present your code here, but I guess you are missing maximizing screen in headless mode.
So I think something like this should solve your problem:
opts.addArguments("--headless", "--disable-gpu", "--window-size=1920,1200","--ignore-certificate-errors");
