the auth.global.nreal.ai URI is the old URI that the Nebula app used to login. After the Nreal to Xreal rebrand you need to install the latest Nebula app.
The latest versions are posted in the thread for people outside of the published area
Hi, please download the V3.5.0 version of Nebula. We have changed the login service so you may encounter the login issue in the older versions (V3.3.0 or below).
