How to fix
Can’t Connect to Battle.net
on Windows

Hello. I need help with the Battle.net app. I was recently forced to update it as per usual, but this time it was all different. I could not launch any games installed via the app - I got the "Can't Connect to Battle.net" error instead. I thought that waiting would help, but it didn't - it's been four days already. Please help.

There have been many players complaining about not being able to connect to Battle.net app for a while now. The online platform was launched by Blizzard Entertainment as early as 1996, although it did not act as a standalone app until 2013.[ref en-1] Since then, it became an integral part of every game released by the company.

Yes, not everybody liked the fact that they needed a launcher to be installed on their computers. Initially, people could play games such as World of Warcraft, Diablo III, Overwatch, Hearthstone, or Call of Duty series, and others, without having it tied to the Battle.net app, i.e., they could simply launch the game via the EXE file.

Unfortunately, a few years ago, every game app was integrated into the launcher app, which meant that if it were deleted, players would not be able to launch any Blizzard Activision game. Having it installed is something that people can survive with, but what to do if Battle.net is stuck on login or results in a loop?

Users claimed that the problem typically showed up after an update for the app, while others said that the issue occurred seemingly out of nowhere. If you can't connect to Battle.net, there could many reasons behind why this is happening. For example, you could have corrupted game or app files, or your internet connection could be unstable.
