Hello @rstonge,
Welcome to the forum!
Since you use docker, and do not use --network host, you should not modify config.yaml of these nodes at all.
So please reset the config for the second node to defaults.
To have an access to your dashboard from another devices you should not publish the dashboard port, use either this method: How to remote access the web dashboard - Storj Docs or [Tech Preview] Multinode Dashboard Binaries
this typo is fixed in the documentation, thank you!
