How To Fix Hearthstone Disconnected From Server Issue

There are various factors that can cause the Hearthstone game on your computer to get disconnected from the server. It could be due to your internet connection, a software issue, or even a setting problem. You will need to perform several troubleshooting steps to fix this.

Hearthstone is a digital collectible card game that’s set in the Warcraft universe. Players will have access to certain cards such as spells, characters, and abilities, which they will build to a 30 card deck. You win the game by dealing enough damage to the opposing player bringing them down to zero life. One of the best features of this game is its cross platform functionality allowing PC games to play with their mobile counterparts and vice versa.

Why do I keep getting disconnected from Hearthstone?

One of the issues that you might experience when playing Hearthstone on your PC is when it is randomly disconnecting from the server. This can be a frustrating experience as it can usually cost you the match.

Some of the error messages you might get are as follows:

Error: “Closed. You were disconnected from the Blizzard services. Please relaunch Hearthstone to reconnect.”

Error: “The game failed to start because your opponent failed to connect. Please Try Again.”

Here’s what you need to do to fix this problem.

Solution 1: Check the server status

The first thing you need to do is to make sure that the game server is not down. You van do this by visiting the Blizzard CS Twitter page as announcements regarding down time or maintenance will be posted here.

If maintenance is being conducted then there’s nothing much you can do but wait for it to be completed.

Solution 2: Restart your networking equipment

There’s a chance that the problem is caused by your local network connection. There might be an issue with the connection between your router and ISP which is causing the connection issue on the game. To fix this, you can try to power cycle your networking equipment which refreshes your connection.

Turn off your computer.

Unplug your Modem and Router from the power source.

Wait for a minute then plug your modem and router back into the power source.

Wait until the lights turn back on

Turn on your computer.

Reconnect your computer to the internet.

Solution 3: Release and renew your computer IP then flush the DNS
