After alot of personal time devoted to the problem and not much of help from support the solution seems to be /flushdns for those who have same problem in future.
After some random time farming AB closes some clients with client timeout error. It only happens on 1-2 accounts usually the same not all. This is what i get :
12:01:37 AM: Close connection: 1.1.1.1:1239
12:01:37 AM: Close connection: 2.2.2.2:1250
12:02:08 AM: Close client by timeout...
Hello. I'm having a strange issue last 3 days my AB when i run it with Universal plugin freezes and the only way is to force close it from task manager. Anyone had any previous experience please help.
