In this guide, we will show you the detailed steps to fix the Client version mismatch error in Heroes of the Storm. This crossover multiplayer online battle arena game has managed to create a niche segment of a loyal fanbase for itself. Battlegrounds from the likes of Warcraft, Diablo, StarCraft, and Overwatch have all made their way over to this game. Likewise, it also beholds quite an intriguing and challenging 5-versus-5 match. However, as of now, users are having to deal with an altogether different challenge.
Various users have voiced their concern that they are getting the Client version mismatch error message while trying to launch Heroes of the Storm. So why is this happening? Well, some of the game servers are buggy and are not being updated in real-time. For example, there are around 7 different US servers for Blizzard, out of which three are currently not working along the expected lines. Since the game randomly allocates a server, so every time you would get that buggy server, you will be greeted with the Client version mismatch error.
So how to resolve this issue? Well, you would have to block those 3 buggy IP addresses. Doing so will leave your PC with no choice but to connect to one of the remaining (and working) addresses. Fortunately, we have already got hold of those issue-causing IP addresses for the US region, so let’s put them on the blacklist right away. This should then fix the Client version mismatch error in Heroes of the Storm.
