Then Squid interactino wit this traffic is a simple test of whether the
client IP address is within your LAN and then blindly shovel the HTTPS
traffic through.

Problems are limited to routing, MTU/MSS misconfiguration somewhere
(network VPM tunnel?), and problems with the endpoints TLS negotiation
(browser or upstream server).

That downgrade not resolving the issue indicates that it is not Squid
related.

As Bruno suggested, probably a change to the routing or firewall systems
that traffic is going through that appeared with the OS version bump. It
is pretty rare to see on small bumps, but can happen.
