AION 2 Temporary Errors: Find the Failing Login Stage
Separate account verification, launcher connection, world entry and chat failures before trying a reversible fix or filing a useful NC support report.
Record the full error code and where it appears before changing settings. A 40309:500 security-registration report, a server connection failure and a chat “Please Try Again Later” message are different problems. Use the matching branch below; no verified universal 40309 repair was found.
Identify the blocked stage
Swipe or scroll sideways to see all columns.
| Where it appears | Useful next check | What it does not establish |
|---|---|---|
| Account website / phone or device security | Save the exact prompt, full code and country selector; use regional account support | A game-file reinstall fixes registration |
| PURPLE download or update | Record launcher service, update step and retry after relevant maintenance | Your account has permission to play a different service |
| Server selection or world entry | Match region and world to a current official maintenance notice | Every regional server is down |
| Already playing, but chat fails | Use the chat-specific recovery below | A phone-verification or login-server fix |
| The application closes / fatal error | Use NC’s separate crash guide | Every crash is a network timeout |
Use one controlled recovery attempt
- Save the exact text, full subcode, time with timezone, selected region/world and failure stage. Keep a redacted screenshot.
- Check the announcement for that exact service. If maintenance covers the attempt, wait for its announced completion before retesting.
- Close and reopen the affected game or launcher once after recording the symptom; repeat the same action with the same account and world.
- If other internet tasks fail too, follow the connection checks linked below. If only account verification fails, keep the account-support branch.
- Keep the before/after result. A different code or a different stage is new evidence, not proof that the first problem was fixed.
Handle the official chat symptom separately
NC’s October 4 known-issues notice describes a “Please Try Again Later” message when sending chat, with incoming and outgoing chat affected. It names changing characters, crossing a loading screen or logging back in as recovery. Apply that advice to this in-session chat symptom; it is not an official 40309 fix.
Why country swaps and routing tools are not a confirmed repair
The independent IsThisGameDown report places 40309:500 during security or phone registration and distinguishes a 101702 one-time-code/device symptom. Its country-selector and PURPLE-route workarounds are player reports; no general cause or standing fix was established. Do not replace accurate account information merely to reproduce an anecdote.
Send a report that support can act on
For persistent server connection failures, NC asks for your current country, when the problem began and your ISP. Add the exact code, stage, service/world, launcher version and attempted change. Send account identifiers privately through official support; a public screenshot should hide them.
Use the connection guide for local-network checks and the account-verification guide for identity/device/phone prompts. A confirmed region-specific outage belongs in the server-status guide.
- Check the connection before comparing routes
Measure the local path and separate it from game-session latency.
- Account, phone and device verification
Use the service-specific account route.
- Regional maintenance and server notices
Check the relevant service notice.

The reviewed independent report associates this with security/phone registration. A universal official cause or repair remains unconfirmed; use the exact service and prompt in an account-support report.
