Brave v1.46.144 & Internet Connection Issues

Brave v1.46.144
Linux Debian Desktop AMD64

Brave browser haphazardly is disconnecting certain websites and not loading them.

Firewall is blocking, nor I gave consent for Brave browser to collect any data.

I had deleted the profile and re-created a fresh one, issue keeps happening.

Why Brave browser is not dependable to browse the internet? I am asking thus I can resolve the issue, and try to utilize the web browser.
