Hi, as a first thing to try, if you use a full URL without the "s" does it allow an insecure connection, or does it immediately switch over to a secure connection? http://192.168.1.1/ ''Background Note: when you put the IP address or any server name in the address bar, Firefox 132 and earlier tried http:// first, but Firefox 133 and later try https:// first.'' ''Now obviously a secure connection is preferred, but if the router wasn't forcing that before, this could explain the new error.''
