Hi @seoslav 👋

Thanks for the issue. I think this is fix on the docker config. We support an option as --max-sessions but the docker config for Hub and Node uses max-session which is incorrect.

I am still experiencing the same issue, and nothing works. The "maxSessions" variable is always set up at 2. Tested on firefox and chrome. I'm using the docker-compose-v3-full-grid.yml file.

I am facing the same issue from my side.

I just fixed this in the main repository, and it will be released in the next couple of days. Please keep an eye on the releases for this repo.
