Custom Environment - Error self signed certificate in certificate chain


Currently I try to install bedrock and sage with flywheel. There is no problem with Preferred installation but I can’t change NGINX conf setting to bedrock. When I try to do custom install nginx, php 7.2, and mysql 5.6. Look like it trying to connect to some place to download the image but got ssl cert error. I am not sure how to fix this. Is local flywheel use an embedded cert or pulling cert somewhere from the system? Is there any ssl cert setting that I can change? any suggestion would be appreciated.

I also encounter this with a corporate environment that does DPI (deep packet inspection) when operating within their network. If the pieces of the blueprint already exist locally (i.e. I’ve previously provisioned one site with same choices) it appears to complete successfully.
