Oculus Browser - Problem receiving/posting web requests

Hi, we have an vr app that is embed on a web app that loads data from a node-express API.
Since the start of this week, more precisely on tuesday, the default quest 2 browser stopped to handle the data from http requests to our API. We can't login, load courses list on website or fetch any data from API inside the WebXR application embedded on the site.

Monday was working well, the next day (in a very bad lucky day that we presented the product to the client), nothing works.

Works well on alternative web browser, like Wolvic.
