connection refused unless I turn off the sandbox

[tcurdt]

It seems the Chrome is launched at Chrome running with pid 26 on port 9222 yet it later fails to connect ChromeLauncher:error connect ECONNREFUSED 127.0.0.1:9222 ...unless I add --no-sandbox.

I checked the docs but I am missing some context to understand if it's OK to just turn the sandbox off.

Given that I am running headless in a docker container I assume it shouldn't be so bad?
