To fix VALORANT Error Code 29, start by checking that Windows Firewall allows VALORANT. Riot Games links Code 29 to a possible interaction between the game and Windows Firewall. Code 43 is less clear: Riot’s current code-specific explanation and recommended fix could not be confirmed from the available official guidance, so treat it as a separate troubleshooting case rather than assuming the Code 29 fix applies.
What is the difference between Error Codes 29 and 43?
| Code | What the available Riot guidance establishes | Best starting point |
|---|---|---|
| 29 | Riot says the code may indicate a problem involving VALORANT and Windows Firewall. Its firewall guidance recommends checking that the firewall recognizes and permits the game. Riot’s firewall article surfaced in Arabic localization and is dated May 9, 2025. | Check Windows Firewall permissions for VALORANT. |
| 43 | A current Riot article explaining this code or prescribing a code-specific fix was not confirmed. | Use general connection checks only if the symptoms point to a network problem; do not assume a particular remedy is official for Code 43. |
How to troubleshoot Error Code 29
1. Check Windows Firewall permissions
Riot’s first recommendation for Code 29 is to make sure Windows Firewall recognizes VALORANT and allows it to run. Confirm the game is permitted in the firewall rules rather than disabling the firewall altogether. The cited Riot article identifies the firewall interaction as a possible cause; it does not establish that it is the cause in every case.

2. Consider other security software
Riot notes that third-party antivirus software running alongside system protections can complicate firewall-related troubleshooting. If you use another security product, check whether it is blocking VALORANT or interfering with its network access. Avoid turning off security protections as a general fix.
3. Move on to general connection checks if the firewall check does not help
Riot’s broader network connection troubleshooting guidance, published January 18, 2022 and surfaced in Polish localization, recommends checking Wi-Fi and the network name and password, running Windows network troubleshooting, reviewing firewall rules, and considering router port forwarding when connection to Riot servers is failing. These are general connection steps, not a confirmed Code 29-specific sequence.

- Consider router configuration only when relevant: Riot’s guidance mentions port forwarding for cases where connection to its servers is failing. Router settings vary, so follow the router manufacturer’s instructions and avoid changing unrelated settings.
4. Treat DNS changes as optional and reversible
Riot’s network guidance suggests considering a public DNS provider, renewing the IP address, and flushing DNS as possible network troubleshooting measures. These are broader connection steps, not proven fixes for either code. Riot cautions that some internet providers block third-party DNS; if changing DNS causes you to lose internet access, restore your previous DNS settings.

A code-specific Riot explanation or fix for Error Code 43 could not be verified. That means it would be misleading to present restarting the game, waiting for server load to ease, or changing network settings as Riot’s current official fix for this code.

If the connection otherwise works, consult current Riot Support guidance for the code or contact Riot Support with the exact error and the steps you have already tried. Do not apply the Code 29 firewall guidance as though it were confirmed for Code 43.
