No way to connect to the chromium extensions website

Description of the issue:
I use an intel MacBookPro produced in 2019 on which I run macOS 12.3.1
On the same MacBookPro I had no problems (under absolutely the same Brave settings) to access the extensions website below. Now I cannot anymore.
Instead, I get the error message:
> This site can’t be reached
> The web page at might be temporarily down or it may have moved permanently to a new web address.
Exact URL of the website in question:
Did the issue present with default Shields settings? (yes/no)
Does the site function as expected when Shields are turned off?
did not try
Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):

Does the site work as expected when using Chrome?
I will never, ever use Chrome, thank you very much.
Brave version (check About Brave):
v1.64.109 (Mar 20, 2024)
