Home Assistant unable to connect with Chrome on Mac OS

Good morning,
I have a problem with Home Assistant, sometimes it’s not accessible with Chrome on Mac OS and with other browsers like Firefox it doesn’t work well and with other systems it works, can anyone help me? I don’t understand, even deleting Chrome history/cache, restarting the system and changing the network, the browser with the remote domain gives me access problems immediately after I enter the user and password of the access account.

every now and then it fixes itself, but it doesn’t work again.

The system is configured with Cloudflare Tunnel which exposes Home Assistant and NGINX which acts as a reverse proxy on an Ubuntu Server virtual machine so as not to directly expose the Home Assistant virtual machine

scheme: chrome (Mac OS) —> Cloudflare Tunnel (Cloudflared on Ubuntu Server) —> NGINX (Ubuntu Server) —> Home Assistant
