Unable to start notebook with Binder

Hi,

When starting the " python-binary-search-assignment"-notebook I get the following information in the log:
Found built image, launching…
Launching server…
Launch attempt 1 failed, retrying…
Launch attempt 2 failed, retrying…
Launch attempt 3 failed, retrying…
Failed to launch image gcr.io/jovian/binder-prod-https-3a-2f-2fjovian-2eai-2fapi-2fgit-2f6f67a876519b484ca635a9d61c3b789a-5f2-2egit-3be257:fc2313cc0c09b7451487a614d7c0e3127a4cac11

The notebook won’t start. Is there a issue with my notebook? For now I’m using Google Colab, but I prefer Binder.

Thanks in advances!
