Togic

Hey, I have a Problem with DayZ. Everytime I want to play on a Server I get this Error. (Player Togic is losing connection) (Togic is my Name ^^) i have deactivated the Firewall etc. so I think it must be something different. Sometimes I can play 10 Minutes, and sometimes I can only play some seconds. I dont know why I get this error. I hope that anybody can help me. Im sorry for grammar failures, but Im from Germany and my English isnt perfect ^^ Thanks for your help Best Regards -Togic
