Network Requirements
Domain: Installation & Setup
Motivation
The install script needs internet access to download Hermes and its dependencies. If you are behind a firewall or proxy, you may need to configure it to allow the download.
Concrete Example
On school Wi-Fi the install fails. You switch to mobile data and it works, because the school firewall blocked the download.
Analogy
Like needing signal to send a message. No signal, no delivery.
