1. Your Internet connection is safe and working.

2. You have been connected to the Core before trying to send code or migrate from Test mode. If the connection fails, please try and follow these instructions.

3. After this, try once again.

4. Referring yourself to these instructions, delete the code that was transferred to the Core.

If despite this, the problem has not been fixed, your software may have a problem.
