Common Errors & Quick Fixes
❌ Invalid username format
Fix: Minecraft usernames must be 3-16 characters long and can only contain letters (a-z, A-Z), numbers (0-9), and underscores (_). No spaces or special characters are allowed. Make sure your username follows these rules.
❌ Network error or connection failed
Fix: Check your internet connection. Ensure you can access the Minecraft API. Try again after a few moments. If the problem persists, check if Minecraft services are experiencing issues.
❌ Rate limit exceeded
Fix: If checking too many usernames too quickly, you may hit rate limits. Wait a few moments before checking again. The application may automatically handle rate limits, but if you see this error, slow down your checking speed.
❌ Application not responding
Fix: If the application freezes or doesn't respond, wait a moment as it may be processing. If it continues to be unresponsive, close and restart the application. Ensure you have sufficient system resources available.
❌ Results not displaying
Fix: Check that you clicked the "Check" button after entering a username. Ensure the username is valid (3-16 characters, alphanumeric and underscores only). Try checking a different username to verify the application is working.
