Epicor Data Discovery 10.2.300.3 config for server

I upgraded a server from 10.2.200.x to 10.2.300.3.

I removed the Epicor Data Discovery (EDD) extension and then tried to reinstall. However, It kept asking me for a domain

I ended up pointing to ERMC.com (our main domain) however the website is hosted on a could service that I do not have access to. Is there a way to configure EDD to only look at the main server?

Thanks for any help.
