No internet Connection but I HAVE Internet Connection

Very often game kicks me out because i don’t have internet and battle.net tells me that too. But my internet connection works fine, I only have this problem on Battle.net. Maybe Blizzard has problems with Ukrainian servers (I’m from Ukraine), but I’m not sure. Has anyone had this problem?

have you tried turning off the internet then turning it back on?

Normal issue with Hearthstone, had it since (hs original) launch a decade ago. I use a wired connection, with a stable 500 mbs down+upload speed, low latency, located in Norway, and I only got this issue with Hearthstone, no other games, though my connection details doesnt matter, this isnt a clientside issue, and has been known for ages, documented across countless threads at this point.
