Cannot login to admin panel of SSO Dashboard

I am unable to get the admin side of the SSO Dashboard to let me log in. All I get in response (after exhaustive trial and error) is

{"error":"ValidationError","message":"Login failed. Invalid token."}

I have looked into what its trying to process and the reason it gives that error is that the token is not sent with the request.

I am working with the github SSO Dashboard repo.
If we could use the webtask version, but with a custom domain name as the sso dashboard url, I would be happy, but that does not seem like a priority to anyone right now.
