Verifying Server Reachability

Published on August 30, 2025

The Scenario

You try to access the Proxmox Web GUI (usually https://192.168.1.2:8006), but the browser says “Site cannot be reached.” You haven’t tried accessing the server yet from the computer your are currently using, and you know that the server is plugged in and was working on your last computer.

Which OSI (Open Systems Interconnection) layer should you check?
