Problem mark as failed after gettig 500 Internal Server Error

I just finished my Lab-Configuration file and when I entered the validation key for the first time I have “500 Internal Server Error”. When I refreshed the page the lab has been marked as failed.
Is there any thing that can be done?

Hi Gerard_01109,

The deadline for Chapter 2 has ended :frowning: Sorry to say we cannot extend it.

Please be more careful for the next deadlines and make sure you complete labs side by side.

Thanks, Kanika
