MariaK/Audio-Course-Certification space is down.

Hi there, a huge thank you to the authors for creating this excellent course. I’ve really enjoyed it.
I did run into an issue while trying to redeem my certificate, and I received the following error message (please see the attached screenshot as well):
```
runtime error
Scheduling failure: not enough hardware capacity
```
Would it be possible to help resolve this? Alternatively, if there's another way to claim the course certificate?
Thanks in advance for your help.

Start by reviewing the reported runtime error, the attached screenshot, and the MariaK/Audio-Course-Certification Space mentioned in the issue. The payload names no repository file or test; done means restoring certificate redemption or documenting a confirmed alternative way to claim the certificate.
