I can't see it in any browser. 404 everywhere.
Sorry the correct address is: http://www.visitlazio.com/osservatorio
That link works. Is your problem still there?
There is security software like Avast, Kaspersky,
BitDefender and ESET that intercept secure
connection certificates and send their own.

You can possibly do a DNS lookup via "about:networking -> DNS Lookup" to see if there are issues with your current DNS server. You can try to power the router off/on. You can try a different DNS server or enable/toggle DNS over HTTPS in Firefox.

You can check the connection settings.
- Settings -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":
