Hey there,

So this error happens for 3 primary reasons.

1. The OS being used is unsupported.

2. There is something affecting the the client’s ability to connect to the service.

For the first reason, the only solution will be to upgrade to a supported operating system.

For the second you can try the following:

Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

In some cases there is a corrupt or misconfigured setting within the router or modem. We cannot say what that might be offhand but the easiest way to resolve these conflicts would be to factory reset the router and/or modem.

You may need to look up your specific model for the steps on how to do this and in some rare cases you may need to have this done by the ISP. Feel free to reach out to them for assistance if necessary.

Try running your system in selective startup mode: https://battle.net/support/article/200483

Create a new administrator account: Blizzard Support - Creating a New Administrator Account

Once the account is created, shut down the computer, wait 60 seconds, restart, log into the new profile and try the app/client.

If that doesn’t solve the issue, then I recommend submitting a ticket with an msinfo attached for further investigation. (instructions for collecting that msinfo report will be on the form.)
