1. Verify game files

Corrupted game files can make the game server refuse the connection from your game client. The server might not be able to detect that game is installed, but files are corrupted, so you can use the game distribution platform game verification system to do so.

For Steam users:

Launch Steam and go to the Library.
Right-click on Tom Clancy’s Rainbow Six® Siege and select Properties.
Select the Local Files tab, and click on Verify integrity of the game files.

For Epic Games users:

Open Epic Games Launcher and navigate to the Library.
Find Tom Clancy’s Rainbow Six® Siege, click the three vertical dots, and select Manage.
