Private server codes failing in training fields can halt progress, but common issues stem from code validation or connectivity problems. Apply these five targeted fixes.
Verify Code Accuracy
Problem: Typos or case sensitivity errors. Fix: Re-enter the code exactly, ensuring no extra spaces or incorrect characters.
Check Server Availability
Problem: Server downtime or access restrictions. Fix: Confirm the private server is online in server settings and verify user permissions.

Update Application Software
Problem: Outdated game versions causing compatibility issues. Fix: Install the latest patches via the app's update feature to resolve code conflicts.
Inspect Network Configuration
Problem: Internet instability or firewall blocks. Fix: Test connection stability and temporarily disable security software to rule out interference.
Restart Training Environment
Problem: Cached errors or system glitches. Fix: Reboot the training fields module or restart your device to clear temporary faults.
