@dcmargo54 IIRC Some advanced routers/firewall allow you to debug the network connection, similar to wireshark; the alternative would be to connect your machine to a separate PC that works as a router (requires two network cards, and some serious hackery in the configuration).
The point is to see what network data (if anything) exits your computer and starts its journey across the network.
I don't see anything to indicate where the problem is in the log; I see that Vivaldi is sending out a TLS Handshake protocol message, but gets no response. As I said, this indicates that the protocol package is filtered out somehow, which would specially be the case if all other secure sites work.
The only thing that can do that is a firewall (I am excluding extensions since there were sockets established, and messages sent).
Hmmm, one possible other thing: External firewalls can filter on both source IP/Mac address and target IP addresses; it might be an idea to try forcibly changing the IP address of your machine.
