I managed to install WPT private instance on CentOS with Docker in an Ubuntu 18.04 LTS container, however the only working browser is Firefox. When I set up Chrome for the test on the server interface it gives the mentioned message: “Error connecting to dev tools interface”. It was installed following the guide available on https://firstname.lastname@example.org/local-webpagetest-using-docker-90441d7c2513
I tried to reinstall Chrome but nothing changed.
Any suggestions on how to fix it in order to use Chrome as well?
