1788940159

Getting AION 2 error 40309:500 while trying to verify your phone number or register your device? The message usually says: “A temporary error has occurred. Please try again later. (40309:500)”. AION 2’s Taiwan official site has also addressed this temporary device registration error. Players commonly encounter it when requesting an SMS verification code or completing account security checks.

AION 2 Error 40309:500

This guide explains what AION 2 error 40309:500 means and how to fix phone number errors, temporary verification failures, authentication problems, and related PURPLE login issues.

What Is AION 2 Error 40309:500?

AION 2 error 40309:500 usually occurs during account authentication, phone verification, or device registration rather than normal gameplay. Players may see it after entering a phone number or requesting an SMS verification code. In some cases, one number works while another triggers the error. Common situations include:

  • AION 2 cannot complete phone verification
  • The SMS verification request fails
  • The verification code does not arrive
  • Device Registration cannot be completed
  • PURPLE cannot complete account authentication
  • The message A temporary error has occurred appears
  • Too many verification requests have been submitted

Since this is mainly an authentication error, reinstalling AION 2 or changing graphics settings should not be the first fix.

How to Fix AION 2 Error 40309:500

AION 2 error 40309:500 is usually related to phone verification, Device Registration, or NC account authentication. Try the following fixes in order.

Fix 1. Stop Repeated Verification Attempts

If you have already clicked Send Verification Code several times, stop requesting new codes for a while. Repeated requests may trigger a temporary verification limit and cause further attempts to fail. In this case, you should:

  1. Close the verification window.
  2. Wait before trying again.
  3. Request only one new verification code when you retry.

This is especially important if you see a verification request limit message.

Fix 2. Check AION 2 and PURPLE Server Status

When multiple players report AION 2 error 40309:500 at the same time, the problem is more likely related to NC authentication or verification services rather than your device. Check:

Wait for the service to recover before trying again. Reinstalling AION 2 is unlikely to help with a server-side issue.

Fix 3. Check Your Phone Number Format

If error 40309:500 appears after entering your phone number, check the number format.

Step 1. Select the correct country or region code.

Step 2. Enter your mobile number without repeating the country code. Remove the leading 0 when required. For example:

  • Local format: 07123 456789
  • International format: +44 7123 456789

Step 3. Request one new verification code.

An incorrectly formatted or unsupported phone number may be rejected before the SMS request is sent.

Fix 4. Fully Restart PURPLE and Sign In Again

A temporary PURPLE authentication session issue may interfere with verification.

Step 1. Close AION 2 and fully exit PURPLE. End any remaining PURPLE processes in Task Manager.

Fully exit PURPLE processes in Task Manager

Step 2. Restart your PC, then open PURPLE and sign in again.

Step 3. Install any pending PURPLE updates, launch AION 2, and retry Device Registration or verification.

Fix 5. Check Your NC Account Security Settings

AION 2 may still require additional authentication even after your NC account has been verified. Check that:

  • Your registered phone number is correct.
  • Your account security information is complete.
  • Any available authentication methods are enabled and set up correctly.
  • Any OTP or additional verification method is linked to the correct NC account.

Then restart PURPLE and try the verification process again.

Fix 6. Check Your Connection to the AION 2 Region

An unstable connection to NC authentication services can cause verification requests to time out.

Step 1. Pause large downloads, close bandwidth-heavy apps, and restart your router.

Step 2. Use a stable Ethernet connection or try another network, such as Wi-Fi or a mobile hotspot.

Step 3. Reopen PURPLE and retry verification.
