We are aware of an issue where some players are receiving a “Failed to Connect to Patch Server” error message when attempting to install/update their game client. To resolve this issue, please try clearing your DNS cache. To do this, follow these steps:
1. Click “Start” and type in "cmd" without the quotes into the “Search programs and files” field. This should display the program “CMD” in the start menu.
2. Right-click on “CMD” in the “Start Menu” and select “Run as an Administrator.”
3. Enter the following command below and press enter: ipconfig /flushdns
This should clear your DNS cache. You may need to perform this command a few times.
If the issue persists, your ISP may be providing old DNS information as some ISPs take longer to update this information.
