For some time now I’m facing the problem of the game stopping to download for the last part.
The download itself goes smoothly, for about 99%, but stops all of a sudden and I receive the message saying “Uh oh, it looks like you’ve lost your internet connection.”
I only seem to have this problem with blizzard games, as steamgames still download without a problem and I don’t face any other problems with my internet.
I’ve deleted and installed the battlenet app and overwatch itself multiple times over a course of +6 months.
Are you using a wireless or wired connection? Battlenet is VERY sensitive to small fluctuations in internet quality. It might be worth following their connection troubleshooting steps as well.
