For the past three days now i have been getting the message saying that it has disconnected from pvp net. It doesnt affect in-game but when im in lobby or queue it can cause me to miss the queue accept message or miss my pick/ban in ranked.
The best fix I found is search for Services in programs and files> then click on the services with the cogwheel > go to IP Helper and Stop the service.
Hope this helps!
Note: Every time you restart your computer you will have to keep doing this. Ii got this from someone else who was having the issue and it seemed to work
