I am not sure If I have been banned, all I know is that I cant connect to the server anymore, I was playing most of the day, then I became quiet busy so i was on and off the computer, then it said I had lost connection to the host, and I have tried to reconnect multiply times before that.

If someone could tell me if I am Banned and why would be a great help, then we could try and move forward with this, or if it is a connection issue.

No worrys I can connect now, sorry for the inconvenience.

It's good that you're able to connect now. For future reference, we need to know which is your account in order to check for bans. The easiest thing is to provide a link to your steam profile page.
