Method 3: Update Your Graphics Drivers

Outdated graphics drivers can also contribute to login failures. Visit the official website of your graphics card manufacturer (Nvidia, AMD, or Intel) to download and install the latest drivers.  After updating, restart your computer and try logging in to Overwatch 2 again.

Method 4: Disable Firewall or Antivirus Software

Firewalls or antivirus software can sometimes interfere with the communication between the game and the servers, leading to login issues.  To resolve this, temporarily disable your firewall or add Overwatch 2 to its whitelist.  Similarly, disabling your antivirus software temporarily might also help.
