FusionAuth requests (curl) might be blocked on certain networks

[nfebe]

The local dev server would fail to reach to make curl connections to FusionAuth and PERHAPS other services on certain network configurations.

I experienced this on an off-grid satellite based network that is LAN-ED to a Wi-Fi router.

Not sure what configuration details about my network that would be worth sharing but ifconfig on the culprit network looks like this :

If for some reason, everything about the environment seems to be okay but you can't login/signup try connecting to a different networks to roll out the possibility of this issue.
