I am new to HtB and am having troubles staying connected to any machine. I was curious if it was an issue with a specific machine so I let a ping run on 3 machines at once and every few minutes my connection from all boxes drops for approximately 5 minutes and then comes back up a few minutes after that. This is extremely frustrating and I can't really do much while this is happening. If anyone has any ideas on how to resolve this I would greatly appreciate it. Thank you.
Note on things I've already tried and haven't worked:
1) switched openvpn to tcp
2) edited /etc/resolv.conf to include "nameserver 18.104.22.168"
3) regenerated my key and rebooted my connection to openvpn
Also, I am a free user and am only trying to connect to active boxes.
