If you use a network optimization tool like ExitLag, make sure the Redirect Login option is turned on before launching. This helps bypass region verification issues.

4. Phone Verification Fix
If the launcher gets stuck on SMS verification:

• Go to your PURPLE profile → Manage Login → Phone Login

Connection & Network Troubleshooting

1. Use a Specialized Game Booster
Regular VPNs often fail to bypass NCSoft region blocks. Tools like GearUP Booster, ExitLag, or WTFast optimize your route to Taiwan servers for smoother logins.

2. Reset Your Network
If authentication still fails, open an Administrator Command Prompt and run:

ipconfig /flushdns  
netsh winsock reset  

Then restart your PC.

3. Check Maintenance Schedule
Aion 2 servers usually undergo weekly maintenance. If login issues persist, check the Aion Global Community Forum or official social channels to see if the outage is widespread.
