}
}
when i run the script npm run browsertest i directly get a connection refused from google chrome. I have already deactivated sandboxing in the browser and disabled all proxies. I have also changed ports, but I just can't figure it out.
Does anyone have a solution? I have Debian 10 as OS
error

Answer 1

Hello I have found a solution. I had several instances running and therefore the npm start then selected a different port than I defined in the test. Have killed all processes on the port and restarted
