Can't Find Certain Gaming Servers

Seeing as how you can connect to it through a hotspot, the server is working. That matches the status showing on Squad Servers and BattleMetrics. The question becomes, what error are you seeing when trying to connect? Is there a way to contact the server operator to inquire if your home IP address was banned for some reason? Have you reached out to support for Squad to see if they have any suggestions?

Additionally, not all servers will respond to pings so that's not a reliable test. Traceroutes won't always show the full path either when servers don't respond to pings. This is quite common. When I tried a traceroute to that server it didn't go through Chicago but instead through Seattle, and a very long circuitous route through Comcasts' network to New Jersey, where the server is located.
