I had this problem and it was because Chrome wasn't running! It wasn't running because it wouldn't start in the docker image I was using. The solution ended up being to change the startup script to start google-chrome-stable using the --no-sandbox flag.

hi @farant , I just check to do curl http://localhost:9222 and I could receive the response from Headless Chrome, so I think it is running now.

Hello @Tin-Nguyen !
I found the problem. As you're using remote debugging, simple-headless-chrome doesn't have an instance for the Chrome that you are connecting. So, (because of a bug) whenever you call the close() method it cannot find the instance to close it.
It's fixed now, and should be working if you try with version v4.3.7. Please let me know if it doesn't work by reopening the issue.
Cheers!
Luciano
PS: I'm interested on knowing if remote debugging works well, as I haven't been able to test it right (it should be the same anyway). So, let me know please if it worked for you.
