Stuck on infinite loop

I'm stuck on an infinite loop.
Cloned the repo exactly, entered my config details, but when I hit login, there is never a server response.
I have a feeling it's due to an unresolved promise. Another option is because I'm on localhost without an SSL certificate?

Start by reproducing the login flow with the reported configuration on localhost, then inspect where the request stops receiving a server response. Check whether the behavior is tied to an unresolved promise or missing SSL, and consider the issue resolved only when the cause is identified and login responds normally.
