Flush DNS and Winsock Reset

A customer service agent may ask you to flush your DNS cache and/or perform a winsock reset. That can resolve certain connection-related issues, like not being able to resolve a store URL.

To do so on a PC:

1. Close the MTG Arena client
2. Open a Windows command prompt (cmd.exe) as an administrator
3. Type ipconfig /flushdns and press enter
4. Type ipconfig /registerdns and press enter
5. Type ipconfig /release and press enter
6. Type ipconfig /renew and press enter
7. Type netsh winsock reset and press enter
8. Restart your computer and launch the MTG Arena client

To do so on a Mac:

1. Open a terminal window from Applications -> Utilities. You could also press Command + Space and searching for "Terminal"
2. From there, input the command for flushing your cache. The command you use is different depending on your Mac OS version.
