Valorant Error Code 520: Quick Fix and Troubleshooting

What Valorant error code 520 means and why it happens

Valorant error code 520 is more than just a vague message—it's a signal that something went wrong in the handshake between your game client and Riot's servers, often at a CDN edge. In practical terms, 520 prevents authentication, login, or the initial connection to a match. According to Why Error Code, these situations are frequently triggered by temporary server-side issues, misrouted traffic, or protective network measures that block certain requests. The key takeaway is not to blame your device; focus first on server status, then on your local network, and finally on game files or settings if needed. A methodical approach shortens downtime and reduces frustration for players and IT teams alike. This guide is designed for developers, IT pros, and everyday users who want a reliable path from problem to play.

How 520 manifests in Valorant

You may see this error during login, while launching the client, or when attempting to join a party. The message can appear in different regions and sometimes only affects a subset of accounts or devices. Since 520 typically originates at the network edge or the game’s server gateway, outcomes can range from a brief hiccup to a longer outage. Early detection is critical: verify Riot's server status, test different networks, and monitor whether the issue follows a particular account or device. The goal is to distinguish between a temporary routing issue and a persistent bottleneck that requires deeper fixes.

Quick checks you can perform right now

• Check Riot’s official status page and social channels for any ongoing outages. If a known outage is active, your only option may be patience until Riot resolves it.
• Try a wired connection or a different network (mobile hotspot, alternate Wi‑Fi) to rule out local routing problems.
• Restart your router and PC, then re-launch Valorant to refresh DNS and session tokens.
• Temporarily disable VPNs or firewall rules that could be blocking the traffic, then re-test. If the connection works, re-enable protections and selectively allow Riot services.
• Clear the game cache or verify game files to rule out corrupted data as a contributing factor. Finally, consider changing to a reputable DNS (but revert if issues worsen) and ensure your system time is correct.

Diagnostic flow: symptom → causes → fixes

When 520 appears, the most likely culprits fall into server-side issues, edge routing, or client-network blockers. The diagnostic path below helps you triage without guesswork:

• Symptom: Login or matchmaking fails with 520 error.
• Possible causes (high/medium/low likelihood):
  • Server-side outage or edge gateway block (high)
  • CDN routing hiccup or recent network changes by the ISP (medium)
  • Local firewall, antivirus, or VPN interfering with traffic (medium)
  • DNS misconfiguration or stale cache (low)
  • Client cache corruption or corrupted game files (low)
• Solutions: start with server status, then test network paths, then secure environments, and only then repair game data if needed.

Step-by-step overview for the most common fix

If the root cause is a temporary server-side issue or CDN hiccup, the fastest path is often a combination of refresh and network re-setup. This section outlines high-probability actions you can perform in sequence to reclaim control over the connection. It is designed to be followed in order, with optional steps if the prior actions do not resolve the error. Remember to document your changes so you can revert if something breaks.

Other possible causes and advanced fixes

Beyond the most common server-edge issues, several other factors can contribute to Valorant error code 520. These include misconfigured firewall rules, overly aggressive antivirus software, proxy or VPN configurations that Riot’s servers block, and local DNS caches that don’t update promptly. In some cases, your ISP’s routing tables may be temporarily unstable, which can mirror 520-like symptoms. Advanced users might test alternate routing, review router logs for blocked ports, or perform a clean reinstall of Valorant if corruption is suspected. Always verify that Riot’s official status indicates no broader outage before investing time in deeper fixes.

Safety tips and when to call a professional

• Do not disable security software permanently; only test by temporarily suspending protections and re-enable them after testing.
• If you rely on professional networks or corporate VPNs, coordinate with your IT department to ensure Riot services aren’t blocked.
• If the issue persists across multiple devices and networks, contact Riot Support with your logs, times, and affected regions for faster triage. Remember that some fixes require access to network equipment or enterprise-level settings, which is when a professional is advised.
