An AION 2 security settings error can prevent you from logging into the game even when your account credentials are correct. Instead of entering the world of Atreia, players may receive security-related messages that interrupt authentication through the PURPLE launcher, blocking access until the issue is resolved.
Fortunately, an AION 2 security settings error is usually temporary and rarely indicates a permanent account restriction. Most cases are connected to authentication server issues, outdated launcher files, device verification conflicts, or temporary security checks triggered by the login system. In this guide, you’ll learn How to fix AION 2 error 0xe0000027?, understand What is error code 40309 on AION 2?, and discover whether server selection matters in AION 2.

What is AION 2 security settings error?
An AION 2 security settings error occurs when the authentication system detects that additional security verification is required before allowing access to the game. This may happen after logging in from a new device, using a different network, changing account settings, or following major launcher updates.
Instead of completing the login process, the PURPLE launcher displays a security-related error, preventing players from entering the game until authentication requirements are satisfied.
Most security errors are temporary and are designed to protect player accounts rather than indicate a problem with the game itself.
Some of the most common causes include:
- Authentication server congestion.
- Device verification failures.
- Security validation timeouts.
- Outdated PURPLE launcher versions.
- Temporary account verification issues.
- Regional authentication service interruptions.
Because multiple security systems work together during login, even a brief communication failure can trigger a security settings error.
Why does the security settings error appear?
NC’s authentication system constantly monitors login attempts to protect player accounts from unauthorized access.
When unusual activity is detected, such as logging in from a new computer, switching internet providers, or connecting from another region, the launcher may request additional verification before allowing access.
Security errors can also appear after large game updates when launcher components require synchronization with the latest authentication services.
In many situations, simply updating the launcher or waiting for authentication services to stabilize resolves the problem.
What is error code 40309 on AION 2?
One of the most common authentication messages associated with security verification is Error 40309.
What is error code 40309 on AION 2? In most cases, it indicates that the authentication servers were unable to complete account verification during login. Rather than signaling a permanent account restriction, the code usually reflects temporary communication problems between the PURPLE launcher and NC’s authentication services.
Players commonly encounter Error 40309 during:
- Launch day server congestion.
- Authentication maintenance.
- Phone verification delays.
- Device registration failures.
- Temporary server outages.
Since Error 40309 is generally authentication-related, it often disappears once verification services return to normal.
How to fix AION 2 error 0xe0000027?
If you’re searching for How to fix AION 2 error 0xe0000027?, start with the simplest troubleshooting methods before making major changes to your account or reinstalling the game.
Follow these recommendations:
- Completely close the PURPLE launcher.
- Restart your computer.
- Install all available launcher updates.
- Verify your internet connection.
- Disable VPN or proxy software temporarily.
- Wait several minutes before logging in again.
These basic troubleshooting steps resolve many temporary authentication problems without requiring additional account verification.
Update the PURPLE launcher
Running an outdated launcher is one of the most common causes of security-related login errors.
PURPLE updates frequently include authentication improvements, security patches, and compatibility fixes released after major game updates. Installing the latest version helps ensure successful communication with the login servers.
After updating, fully restart the launcher before attempting another login.
Check authentication service status
Many security-related errors originate on the authentication servers rather than your own computer.
If multiple players report login problems at the same time, checking official service announcements before changing account settings can save considerable time. Authentication services often recover shortly after maintenance or periods of unusually heavy traffic.
It’s also important to remember that a stable connection becomes even more valuable after authentication succeeds. Once you’re able to log in, network quality directly affects raids, PvP combat, and world exploration. ExitLag helps optimize your connection by selecting more efficient network routes, reducing ping, minimizing packet loss, and delivering a smoother gameplay experience throughout your AION 2 adventure.

Advanced troubleshooting for AION 2 security settings error
If the basic troubleshooting steps didn’t resolve your AION 2 security settings error, there are several advanced methods that can help restore access to your account. Most security-related issues are caused by temporary authentication problems, but local settings can sometimes interfere with the verification process.
Work through each solution individually before making additional changes to your account or launcher.
Verify your network environment
The authentication system relies on secure communication between your device and NC’s servers.
Before logging in again, try the following:
- Restart your modem and router.
- Connect through a wired Ethernet connection whenever possible.
- Temporarily disable VPNs or proxy services.
- Close applications that consume significant network bandwidth.
- Restart your PC before opening PURPLE again.
These steps eliminate many local connection issues that may interfere with account verification.
Clear the PURPLE launcher cache
Corrupted launcher data can occasionally prevent security validation from completing successfully.
Completely close the PURPLE launcher before clearing its temporary cache files. When the launcher starts again, it creates fresh authentication data, allowing the security verification process to begin from scratch.
If the issue continues, reinstalling only the PURPLE launcher is usually sufficient. Reinstalling the full AION 2 client is rarely necessary for authentication-related errors.
Does server matter in AION 2?
Yes, but not in the way many players expect.
Your selected game server affects character progression, latency, and matchmaking, but it usually does not cause authentication or security settings errors. Login verification happens before you connect to an individual game server, using NC’s authentication infrastructure instead.
However, during major launches or maintenance periods, authentication services may experience congestion that affects every server simultaneously. In those situations, waiting for the login services to stabilize is often the fastest solution.
Choosing a server closer to your physical location can still improve gameplay after you successfully log in by reducing latency and improving connection stability.
What is the phone number error in AION 2?
The phone number error is another authentication-related issue that occurs when the verification system cannot successfully confirm the mobile number associated with your NC account.
This error is commonly caused by:
- Delayed SMS verification codes.
- Authentication server congestion.
- Incorrect phone number formatting.
- Expired verification codes.
- Temporary regional verification restrictions.
Although this issue differs from an AION 2 security settings error, both are handled by the same authentication services and often appear during periods of heavy server traffic.
Comparison of the most effective solutions
Different security problems require different troubleshooting methods.
The table below summarizes the most effective fixes.
| Solution | Best used when | Difficulty | Expected effectiveness |
| Wait for authentication recovery | Server congestion | Easy | High |
| Update the PURPLE launcher | After major patches | Easy | High |
| Restart your network | Local connection issues | Easy | Medium |
| Clear launcher cache | Authentication failures | Medium | Medium |
| Disable VPN temporarily | Security verification conflicts | Easy | Medium |
| Contact NC Support | Error continues for several days | Medium | High |
Working through these solutions from simplest to most advanced generally resolves authentication problems without requiring a complete reinstall.
