6. Check the Internet Connection
The chances are also applicable that your internet connection somehow has an issue with slow speed or stability. It’s better to run a speed test of the connected internet online and try playing other multiplayer games. If in case, there is an issue with the internet connection at your end, try switching to a wired (ethernet) connection from Wi-Fi or vice versa to cross-check the issue.
Contact your internet service provider (ISP) to get it checked, and ask to fix the issue. You can switch to a different ISP or upgrade to a higher plan.

- Power Off the Wi-Fi Router completely > Disconnect the Power Cable from the router and power source.
- Wait for a few minutes, then reconnect the power cable.
- Now, Power On the router > Connect to the Wi-Fi network and check for the issue.

It would be best if you also tried allowing the Warzone 2.0 game program in the Windows Firewall protection by following the steps below to reduce startup crashes, server connectivity errors, etc.
- Open the Start menu > Search for Control Panel and open it.
