@Gil38792445205p have you checked/tried the following?
1. Check your network connection if on WiFi - make sure you are connecting to 5 ghz and not dual band/2.4 ghz.
2. Tried accessing with another browser.
3. Checked for browser updates and confirmed no pop up blockers active.
4. Id say check your firewall/Win Defender but it appears you can ping the site.
