Hs doesn't update on ethernet connection

When I use ethernet I can’t update hearthstone because it gets stuck at initializing and stays like that for hours. When I switch to my phone’s internet, update starts without a problem. But I am out of mobile data since I used it to update hs last week. So how can i update with an ethernet connection? Btw I tried most of the solutions on the internet such as reinstalling deleting cache flushing dns, removing firewalli running as admin etc. Thanks for your interest.

You should be posting on the Hearthstone Technical Support forum.
