External Oauth supported? URI?

Hi, quick question. I deployed a private space demo of a python/docker app (chainlit based). It has OAuth support I’ve set up for Google, and is working on other deploys and locally.

My auth page does come up fine. Actually logging in was taking me to an error page as expected till I narrowed down the redirect URI. Once I got that as best I could, it looks like it should be working but is blocked or something. The button just pushes but appears to do nothing.
I’ve tried redirect URI bases of https://huggingface.co/spaces/MYACCOUNT/MYSPACE/auth/oauth/google/callback
as well as

Is this something that is just plain blocked or any idea what I might look at help?

Thanks in advance!
