I am not the one to give up quickly, but man oh man, WHAT IS GOING ON? I have managed to pinpoint the problem down to something to do with the iptables but after completely fucking up my firewall I still dont know what is going on. I flushed iptables and tried restarting docker – didn’t help. I then reinstalled ip tables and tried again- didnt help. I tried looking on the web couldn’t find anything to solve the problem, even tried the GPT Could anyone provide some assistance on this?

Also tried this: systemctl start docker – Job for docker.service failed because the control process exited with error code

Could it be that the OVPN server that I am running?
