Network connection between proxy and client broke (network cable
unplugged, wireless disconnected, or something to similar effect).

Client disconnected. Similar to the above.

Exactly so. "connection too slow" is both the problem and what the
message means.

Exactly so. "connection too slow" is both the problem and what the
message means.

It can happen in a number of ways:
* web browser "Happy Eyeballs" mechanism
* network congestion
* buffer bloat
* wireless interference (if any of the links are wireless, Wifi etc)
* overloaded proxy not responding fast enough to keep the cleint from
disconnecting
* broken firewall somewhere
* broken HTTP middleware
* read/write timout values configured too low for your network
requirements

Note these are *all* generic networking problems. Other than the small
possibility of misconfiguration there is nothing particualrly related to
Squid in the reasons for those errors happening.
