Connection Lost - when clicked on "Create Workflow"

Questions
1

Hi. I just created a Google VM and configured n8n using Docker. (Debug info below.)

I created SSL and all basic functionality started but as soon as I click on “Create Workflow” then in red “Connection lost” starts appearing on right side top. Though I can add nodes but can’t test anything.

Is there anything missing in what I am doing or is it a known issue with this version?

Thanks
