Can't connect to target - Introduction to Threat Hunting & Hunting With Elastic / Hunting for Stuxbot

Module: Introduction to Threat Hunting & Hunting With Elastic, Hunting For Stuxbot
Task: Navigate to http://[Target IP]:5601 and follow along as we hunt for Stuxbot. […]

I’m connected to the VPN, waited for at least 5 minutes and can’t connect to the given IP / Port with Firefox. Restarted the target three times with no luck. Tried to reach another host from a different module / task and that worked. No proxy is configured in Firefox.

Solved it by changing the academy vpn server.
