Error connecting to dev tools interface

Hi there,

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://medium.com/@francis.john/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?

Thanks.

I see the same issue. it works with firefox but if ur test is being run for synthetic monitoring and runs every couple of minutes, after a few days, even firefox starts to give errors.
