Local Router Error - Service error 502 - Windows 8

I am Using the latest version Local Flywheel on Windows 8. I am trying to migrate my live site to a local host and running into this problem. I think it’s a timeout, but I am unsure how to fix it since I’m completely new to NGINX.

I have been reading up for the whole day, but can’t find no solution.

This is preventing me from restoring my site, and it keeps happening in other places - hence me guessing its a timeout
