Can’t seem to get around it not completing the download nor updating afterwards.
Moreover, the launcher itself isn’t loading games at all but showing an error: “Oops! Something went wrong. We had trouble loading your content.”, with a reload button.
Battle.net is bricked, it seems.
Sounds like Battle.net is stuck! It won’t download updates, games won’t load, and you’re getting a “Something went wrong” error. Don’t worry, this happens sometimes. Try a quick restart of your PC first. If that fails, try some troubleshooting steps from Blizzard’s support site (search “BLZBNTAGT00000000” for general download errors). Hopefully this gets you back online!
