Frequently Asked Questions

Why does OpenVPN keep saying AUTH_FAILED even with correct credentials?
This usually happens when your account has expired, been suspended, or when using outdated configuration files. Check your account status with your VPN provider and download fresh configuration files.
Can firewall settings cause OpenVPN AUTH_FAILED errors?
Yes, overly restrictive firewall or antivirus settings can block the authentication process. Temporarily disable these programs to test, then whitelist OpenVPN if the connection works.
How do I fix AUTH_FAILED when using two-factor authentication?
Some OpenVPN clients don't properly handle 2FA. Try temporarily disabling 2FA, test the connection, then contact your VPN provider about proper 2FA configuration for OpenVPN clients.
What should I do if AUTH_FAILED happens only with specific servers?
Try connecting to different server locations. If only certain servers fail, the issue is likely server-specific maintenance or configuration problems. Contact your VPN provider to report the problematic servers.
How often should I update my OpenVPN configuration files?
Update configuration files whenever you experience connection issues or at least every 3-6 months. VPN providers regularly update server settings and security protocols that require fresh configuration files.
