Hi, I'm trying create a local Prefect system to present to my employer. Using a Windows 10 VM I can get things working without issue. To create the demo I need to interact with other systems on the company network... which is where the problems start. The web UI only shows buttons, which do not respond. These are the steps I take to reach this point: • Start Docker • Cmd prefect backend server • Cmd prefect server start • Browser (Edge & Chrome) localhost:8080 The debug from the browser gives the error: Uncaught (in promise) Error: passed invalid or empty tenant object My company laptop connects uses a proxy, I'm not sure if this is related to the issue

Hi @David Glaister, what version of Prefect did you use? I also just wanna make sure you know that Prefect Cloud gives you 10000 free task runs every month, and that’s a lot easier and more than enough to get started.

Thanks for the reply Kevin, Sys info: Windows Version: 20H2 (OS Build 19042.98) with WSL2 Prefect Version: 0.14.19 Docker Engine: 20.10.6 Python 3.7.9 docker-compose: 1.29.2 Initially I'd like to get the demo running locally, to get servers, networks, ports, firewalls etc. access to the outside world and signed off would take months.

I’ll bring this up to the team and get back to you

@David Glaister can you visit localhost:4200/graphql ?
