Hi

I suspect the AVAST firewall, initially.

However...

asuswebstorage.com

WHOIS Information

IP Address: 210.65.113.35

210.65.113.35 doesn't support a secure connection with HTTPS

• Attackers can see and change information that you send or receive from the site.
• It's safest to visit this site later if you're using a public network.
• There is less risk from a trusted network, like your home or work Wi-Fi.

So it may be the browsers deciding that the site is via HTTP and not truly HTTPS compliant.

Maybe a better browser like DuckDuckGo, or Brave may yield results.

If in doubt please ask.
