I get “Error code: BLZBNTBNA000003E8” when trying to connect to Battle.net through the Battle.net app. I simply cannot log in. The Battle.net works, but fails to connect regardless if this is through WiFi or via an Ethernet cable connection.
I updated both the Battle.net and Hearthstone apps, and after that I was never able to log in to my Battle.net account on my mac Mini, thus rendering Hearthstone unplayable. Funny that I was still able to play Diablo 3 accessing it directly, rather than through the Battle.net app.
So the real issue is that Battle.net cannot go online, and as such shows “Error code: BLZBNTBNA000003E8”. In other words, the Battle.net app does open, but it simply cannot connect.
I also opened a ticket and exposed the issue. I followed all of their suggestions, but nothing work, yet they would continue to claim things like that my Internet connection was having issues, which was not the case, as my iPhone was still able to connect and run Hearthstone without issues under my same Internet service. They also wanted to blame it on me not updating my operating system, yet setup still meets the minimum requirements:

P.S. - At least I’ve been more productive with my life ever since I couldn’t log in to Battle.net .
