Are you using nix with your build?

What issue are you getting with localhost:3100? I found it confusing at first, but it seems like 3100 is just for the frontend. But that’s a whole separate build to get that running.

Connect-explorer-to-mainnet is just the backend and uses ports 8000, 8100, 8110.

Can you not get connect-explorer-to-mainnet to run and that’s why you’re rebuilding?
