The steps usually include: open Windows Security, go to Firewall & Network Protection→ Allow apps through Firewall→ Find Valorant or Vanguard related items and make sure they are allowed in all network environments. At the same time, turn off third-party security software such as 360 Security Guard and McAfee, and try the game again when finished.
