Hello
I’m currently working through the CTPS and I’m 30% of the way through.
I’ve noticed many times throughout the process that an exploit will work on the Pwnbox and not on my workstation, which can be frustrating after hours of changing syntax to learn you had it right the first time 
Most recently, trying to exploit Apache Druid, using Metasploit wouldn’t work on my workstation but worked instantly on the Pwnbox.
To my knowledge everything is configured correctly; I refresh my ovpn config file regularly, resolv and hosts are as they should be.
Does anyone else share this issue? Or can anyone shed some light on the potential underlying issue here?
Thanks
