Launching Github repo into Binder fails

Hi!

When trying to launch my GitHub repo into Binder on a specific branch, I got the error message of

Spec is not of the form "user/repo/ref", provided: "https%3A%2F%2Fgithub.gatech.edu%2Fjzhan44%2Fcs6440_forgetful_spiders/voila_deployment_testing". Did you mean "https%3A%2F%2Fgithub.gatech.edu%2Fjzhan44%2Fcs6440_forgetful_spiders/voila_deployment_testing/HEAD"?

My repo says that it is public, and I think I have the repo URL of https://github.gatech.edu/jzhan44/cs6440_forgetful_spiders correctly input, so I am not sure what could be going wrong.

Current inputs:

GitHub repository name or URL:
https://github.gatech.edu/jzhan44/cs6440_forgetful_spiders

Git branch, tag, or commit: voila_deployment_testing
Path to a notebook file (optional): project.ipynb

Thank you so much in advance for any help!

That isn’t a public repo. https://github.gatech.edu/ probably requires campus sign-in.
You can always try it from an incognito browser window and/or off your campus network to try and test.
