Gateway not detected

I have an issue that appeared recently regarding Cloudflare Zero Trust, and a protected resource. I have a page that requires for users to be connected via a gateway (zero trust enrolled warp client) to access a resource.

When I go to the protected resource, I am faced with the following:
403 error - Forbidden
WARP: on
Gateway: off

However, when I go to, I get the following:

The device from which I am accessing a resource has Cloudflare Zero Trust client enrolled (the device shows as online in the admin panel)

This is a relatively new issue, as it appeared recently, without any changes to the configuration that was previously working fine. Sometimes, I am allowed to access a resource, but after a few seconds when I make a new request I get a 403 forbidden error. Is there anything I can do to solve this issue?
