Thank you wimmme, you have the right client version. We solved some client reconnection issues in previous versions but those shouldn't occur anymore. But something strange really happens at your environment. We will try to find the actual source of problems. If you would like to help us, there is another piece of information we would appreciate to obtain. There is a separate log for the transport layer between avast! Administration Console and clients. It may be found on the client side at %ProgramData%\AVAST Software\Avast\log\sbctransport.log. When the problem reoccurs (e.g. on precheemek.xtenso.local), could you attach that log file here? There should definitely be some strange error messages in there after such many reconnect attempts (one per second). Thanks again. Jan.
