Battle Net App keeps disconnecting constantly

Hi, i have very annoying problem with BN application, it keeps disconnecting every few minutes and even seconds sometimes. This is happening even when i literally do nothing on my pc, i log in to Bn, and i just go to get my drink or some food i come back and it is already disconnected, sometimes unable to log in again untill i wait certian amount of time. Whan i open main youtube page for example it is guaranteed dc, when i download new addons dc, literally smallest action that requires some use of connection dcs my bnet. I checked if that happends to steam, or gog, origin but no, they are all fine, it is only BN. I got freshly installed win10 64b, with all the latest drivers/updates. Anyone having the same issue, or got any idea how to fix it?
