Removed access writeups?

I was pushing a vbd challenge to the repo as usual. But today i got

$ git push origin +danmur97
remote: You are not allowed to push code to this project.
fatal: unable to access ‘’: The requested URL returned error

Why is this happening?

Just a security measure that we have for trainees that grants access to the repo only for a limited time. We will grant you ASAP full developer access again.

Sorry for the inconvenience.
